Best Kindle Deals Review: Which Model to Buy

The best Kindle deal for most people in 2026 is the 7-inch Paperwhite. It is the cheapest model in the current lineup that combines a 300 ppi display, an adjustable warm front light and an IPX8 water-resistance rating, and those three features are the ones you notice every single day rather than on a spec sheet. Buy the 6-inch base Kindle instead only if you read indoors, never near water, and want to save real money — it still renders text at 300 ppi, so you lose comfort features, not sharpness. Buy a Kids bundle rather than a standard Paperwhite if a child will use the device, because the cover and the multi-year replacement guarantee usually land inside the same price band. Step up to a Scribe only if you annotate PDFs or take handwritten notes. This best Kindle deals review weighs screen size, pixel density, front-light warmth and waterproofing against price tier, then walks through twelve Kindle-edition titles worth loading onto whichever model you pick — from NCLEX and SAT prep to literary fiction and management handbooks.

Top 3 Picks

Best overall: Saunders Comprehensive Review for the NCLEX-RN Examination – E-Book. If you are buying a Kindle mainly to study, this is the single title that justifies the purchase on its own: it covers the entire NCLEX-RN test plan in one volume, and search plus X-Ray turns a thousand-page brick into something you can query in seconds. Pair it with a 7-inch Paperwhite or a Scribe.

Best budget: PTCB Exam Study Guide. Five full-length practice tests and 450+ questions for a budget-tier price, and the question-drilling format translates to e-ink far better than a diagram-heavy reference does. A 6-inch base Kindle is genuinely enough for this one.

Best premium: Harvard Business Review Manager’s Handbook. The most re-readable title in this roundup and the one that holds up as an ongoing reference rather than a one-and-done exam cram, which is what you want if you are spending premium money on a book you will open for years.

Quick Comparison

Every title below is a Kindle edition, so the format questions are the same across the board: reflowable prose is comfortable on any screen size, while tables, diagrams and question sets reward a larger panel. Price tiers are bands, not quotes — listing prices on e-books move constantly, and exam-prep titles in particular get discounted hard in the weeks before test dates.

How We Chose

Selection started from the reader’s job, not from a ranking. For a device, the criteria were the four things that change daily use: screen size (6, 7 or roughly 10 inches), pixel density (300 ppi versus the older 167 ppi panels still circulating second-hand), front-light warmth (an amber-adjustable layer versus a fixed white one), and water resistance (an IPX8 rating versus none). Price tier was then mapped onto those four, because the honest answer to “is the upgrade worth it” depends entirely on which of the four you personally use.

For the titles, the criteria were category fit, format fit and upgrade path. Category fit means the book does the job its title claims — a test-prep book needs practice questions, a handbook needs to be worth reopening. Format fit means how the title behaves as reflowable e-ink text: continuous prose survives a 6-inch screen, while dense tables and diagrams push you toward 7 inches or a Scribe. Upgrade path means whether a cheaper alternative in the same category covers 80 percent of the same need. Every judgement here comes from published specifications, the structure each listing describes, and documented behaviour of e-ink displays — not from testing units or from owning the titles.

1. Saunders Comprehensive Review for the NCLEX-RN Examination – E-Book – Best for Comprehensive NCLEX-RN Prep

This is the title to buy when you want one book covering the whole NCLEX-RN test plan rather than a stack of narrow guides. It suits final-year associate and baccalaureate nursing students, repeat test-takers who already know their weak content areas and want a single authoritative reference to fill them, and internationally educated nurses preparing for the exam. As a Kindle edition it becomes something a print copy can never be: a searchable clinical reference you can carry through a twelve-hour clinical shift without a tote bag.

Key specs

• Format: e-book edition of the Saunders comprehensive NCLEX-RN review
• Scope: the entire test plan — medical-surgical, pharmacology, maternal and newborn, paediatric, mental health, leadership and management
• Structure: content chapters followed by review questions with answer rationales in the Saunders house style
• Bulk: the print counterpart is one of the thickest single-volume NCLEX reviews on the shelf, well past a thousand pages
• Publisher: Saunders, the nursing imprint behind the most widely assigned review series in RN programmes
• Reads best on: a 7-inch Paperwhite for prose, or a Scribe if you want to annotate question sets by hand

What it does well

The value of a single-volume comprehensive review is that it removes the decision of where to look. When a practice question on heart failure medications goes wrong, the explanation, the drug class, the assessment findings and the related test-plan category all live in one place instead of being split across a pharmacology guide, a med-surg guide and a question bank. On e-ink, that consolidation gets sharper: searching a drug name or a condition jumps you straight to the relevant chapter, and highlighting a rationale keeps your revision trail visible without sticky notes. It is also the title in this roundup that benefits most from a warm front light, because the realistic use case is an hour of dense reading at 11 p.m. after a shift.

Pros

• Covers the full NCLEX-RN test plan in one purchase instead of several
• Rationales explain the reasoning, which is what actually transfers to the exam
• Search and X-Ray make it usable as a clinical reference, not just a study book
• Prestige imprint means the content aligns with what RN programmes already teach

Cons

• Premium tier — the most expensive title in this roundup by a clear margin
• Density is punishing; reading it cover to cover is not a realistic plan
• Small tables and figures are cramped on a 6-inch screen
• E-ink page turns are slower than paper when you are flipping between a question and its answer

How it compares

The nearest alternative here is Fundamentals of Nursing – NCLEX-RN Exam Review, which offers 349 practice questions with rationales at a budget price. The two are complements, not substitutes: Saunders is the reference you consult when you do not understand something, and the question book is the drill you run when you do. If your budget only stretches to one, buy Saunders first — a question bank without the underlying content is a score tracker, not a teacher. Against the Princeton Review test-prep titles, Saunders is a subject-matter reference rather than a test-mechanics guide, and it has no adaptive online component at all.

2. Princeton Review SAT Premium Prep, 2027 – Best for Full-Length SAT Practice

This suits a student who has already decided to take the SAT seriously and wants volume of practice above all else. Six full-length practice tests — three printed in the book and three adaptive tests delivered online — is the headline, and it is a genuine differentiator because most competitors stop at two or three. It fits a junior or senior in the middle of a score-improvement push, and it fits parents buying one resource rather than assembling a course.

Key specs

• Format: e-book edition of the Princeton Review SAT premium preparation title
• Practice volume: 6 full-length practice tests, split 3 in the book and 3 adaptive online
• Edition year: 2027, i.e. built for the current digital SAT cycle
• Extras: online tools tied to the book, plus strategy and review chapters
• Structure: strategy first, then content review, then full-length practice
• Reads best on: any size, but the practice tests themselves belong on a tablet or paper

What it does well

The premium tier here buys test count, and test count is the single most reliable predictor of score improvement because it exposes you to the pacing problem. The digital SAT is adaptive, which means the second module’s difficulty depends on how you performed in the first — a mechanic you can only internalise by sitting full-length adaptive tests under time pressure. The book’s review chapters are competent and readable on a Kindle, and because the prose is continuous rather than diagram-heavy, a 6-inch base Kindle handles them without complaint. The honest caveat is that a Kindle is the wrong device for the practice component: the digital SAT is taken on a computer, so the three online adaptive tests should be taken on a laptop, and the three in-book tests are best printed or worked on paper so you can annotate freely.

Pros

• Six full-length tests is more practice volume than most competitors at this tier
• Three of the six are adaptive, matching how the real digital SAT behaves
• Current-cycle edition year, so the content is not chasing an old format
• Strategy chapters read cleanly as reflowable e-ink text

Cons

• Premium price for what is, in practice, a workbook
• The core value sits in tests you will not want to take on a Kindle
• Answer-key flipping is clunky on e-ink compared with paper
• Overlaps substantially with the PSAT title below if you are taking both exams

How it compares

Against Princeton Review PSAT/NMSQT Prep, 2026, this is the bigger and more expensive sibling: same publisher, same digital-test philosophy, but more practice tests and content pitched at the harder exam. If you are a sophomore taking the PSAT as a rehearsal, buy the PSAT title and save the money. If you are a junior or senior whose PSAT score is already in hand and who is now aiming at the SAT itself, this is the one. Against the NCLEX titles in this roundup, the contrast is instructive: nursing prep rewards a single deep reference, while SAT prep rewards repeated timed rehearsal.

3. Princeton Review PSAT/NMSQT Prep, 2026 – Best for Digital PSAT and NMSQT Candidates

This is for the student taking the PSAT/NMSQT — typically a sophomore or junior — and for the parent who wants one book rather than a tutoring contract. It bundles three practice tests with content review and online tools, and it is explicitly built around the digital PSAT, which is a different animal from the paper version that most adults remember. It suits a first serious exposure to standardised testing more than it suits a student chasing a perfect score.

Key specs

• Format: e-book edition of the Princeton Review PSAT/NMSQT preparation title
• Practice volume: 3 practice tests
• Edition year: 2026, aligned to the current digital PSAT cycle
• Extras: online tools and additional digital practice material
• Structure: strategy, content review, then timed practice
• Reads best on: a base Kindle for the review chapters; a laptop for the tests

What it does well

The most useful thing this book does is teach the digital interface before test day. The digital PSAT runs in a locked-down testing app with its own annotation and flagging tools, a built-in timer and a calculator that behaves differently from the one on your phone. Students who lose points on the PSAT usually lose them to interface friction rather than to content gaps, and a book that walks through the on-screen mechanics is worth more than another hundred vocabulary words. Three practice tests is a sensible volume for an exam that most students sit once or twice, and the review chapters are written for a reader who is not yet a test-taking veteran. As an e-book it reads well on a small screen, though you will want the practice tests on a laptop to match the real conditions.

Pros

• Three practice tests is proportionate to an exam most students sit once
• Digital-first framing matches how the PSAT is actually delivered
• Online tools extend the book beyond its printed pages
• Cheaper and less intimidating than the SAT premium title

Cons

• Still premium tier for a book with only three tests
• Content ceiling is lower than the SAT title, so high scorers outgrow it
• The online components need a separate device, splitting the workflow
• If you are already sitting the SAT, this is largely redundant

How it compares

The direct alternative in this list is the SAT Premium Prep, 2027 title. Choose the PSAT book if the PSAT is your next scheduled exam, the National Merit cutoff matters to you, or you are buying for a student who has never taken a timed digital test. Choose the SAT book if you have already sat the PSAT and are now preparing for the real thing — the extra three tests and the harder content are worth the premium. Neither book substitutes for the other’s online components, and buying both means paying twice for overlapping strategy chapters.

4. NCLEX Pharmacology: Essential Drug Review Guide – Best for Fast Drug-Class Lookup

This suits a nursing student in the last mile of NCLEX preparation who keeps missing pharmacology questions, and equally a working nurse who wants a compact drug-class refresher. It is deliberately narrow: pharmacology only, organised for lookup rather than for a linear read. That narrowness is the point — if you already own a comprehensive review, this fills the single gap that comprehensive reviews handle worst, which is the sheer volume of drug classes you are expected to hold in memory.

Key specs

• Format: e-book edition of a pharmacology-focused NCLEX review guide
• Scope: drug classes, mechanisms, key side effects and nursing considerations
• Series: part of a set of NCLEX essential review guides
• Organisation: reference-style, built for targeted lookup rather than cover-to-cover reading
• Length: substantially shorter than a comprehensive review
• Reads best on: a 7-inch Paperwhite, because drug tables reward the wider panel

What it does well

Pharmacology is the topic where a search index beats a table of contents, and this is exactly the kind of book that benefits from being digital. When a practice question asks about a beta blocker in a patient with asthma, you want the class, the contraindication and the monitoring parameter in one screen, not three chapters apart. A dedicated pharmacology guide keeps that information grouped the way exam questions test it — by class and by body system — rather than scattering it through med-surg chapters. The mid-range tier also makes it the cheapest way to patch the weakest area of a comprehensive review you already own. On a warm-light Paperwhite it is comfortable for a twenty-minute targeted session, which is realistically how this book gets used.

Pros

• Narrow scope means less hunting for the drug information you actually need
• Mid-range price fills a gap without duplicating a full review purchase
• Reference layout suits e-ink search and bookmarks unusually well
• Useful after the exam as a workplace refresher, unlike pure question banks

Cons

• Pharmacology only — it will not carry you through the rest of the test plan
• Drug tables are the least e-ink-friendly content type on a small screen
• Less practice volume than the question-drilling titles in this list
• Content depth varies by drug class, as with most single-topic guides

How it compares

Against Saunders Comprehensive Review for the NCLEX-RN Examination, this is a scalpel versus a toolkit. Saunders contains all of this information somewhere, but finding it costs you time you do not have in the final fortnight. Buy the pharmacology guide as an add-on if you are already using Saunders; buy it instead of Saunders only if pharmacology is your sole weak area and you are otherwise confident. Against the fundamentals question book, the split is the same as everywhere else in exam prep: one teaches, one tests, and the best results come from pairing them.

5. PTCB Exam Study Guide: Pass the 2026 PTCE on Your First Attempt – Best Budget Pharmacy Technician Prep

This is aimed at pharmacy technician candidates sitting the PTCE, and at anyone already working in a pharmacy who needs certification to move up. Five full-length practice tests and 450+ questions at a budget price makes it the highest question-count-per-dollar title in this roundup. It suits a self-directed candidate who wants repetition and a clear exam-cycle date rather than a broad educational programme.

Key specs

• Format: e-book edition of a PTCB exam study guide
• Practice volume: 5 full-length practice tests
• Question count: 450+ questions, in the listing’s own count
• Exam cycle: built for the 2026 PTCE
• Structure: practice tests plus supporting review content
• Reads best on: a 6-inch base Kindle — question text reflows fine at small sizes

What it does well

The PTCE rewards breadth and speed more than depth, which makes high-volume question practice the correct strategy, and this book is built around exactly that. Five full-length tests let you simulate the real sitting more than once, which matters because pacing problems only show up under full-length conditions. At the budget tier it is also the easiest recommendation in this roundup to make unconditionally: there is no cheaper way to get this many timed practice questions, and the content is current to the 2026 cycle rather than a recycled older edition. Because the material is question-and-answer rather than diagram-heavy, it is one of the few test-prep titles that genuinely works on the smallest Kindle screen.

Pros

• Best questions-per-pound ratio of any title here
• Five full-length tests supports repeated timed rehearsal
• Current 2026 exam cycle, not a relabelled older edition
• Question text reflows cleanly on a 6-inch screen

Cons

• Question volume does not substitute for teaching if your knowledge base is thin
• Fewer explanatory diagrams than a full course text
• Answer keys and explanations are fiddly to navigate on e-ink
• Budget presentation; it is a workbook, not a reference you will keep

How it compares

The closest comparison in this list is Fundamentals of Nursing – NCLEX-RN Exam Review, which applies the same drill-first philosophy to a different credential with 349 questions. Both are budget-tier, both are question-led, and both pair badly with nothing and well with a comprehensive reference. If you are choosing between the two, the deciding factor is simply which exam you are sitting — there is no meaningful overlap in content. Against the premium NCLEX titles, the trade is clear: you give up the explanatory depth and gain enough practice volume to make the real exam feel routine.

6. Stoner (New York Review Books Classics) – Best Literary Fiction for a Light Device

This suits the reader who wants one genuinely great novel on a device that weighs less than a paperback, and who is buying a Kindle for pleasure reading rather than for study. John Williams’s novel about a Missouri farm boy who becomes an academic is the kind of quiet, character-driven book that the NYRB Classics line exists to keep in print, and it is a natural fit for e-ink: continuous prose, no diagrams, no colour, no tables.

Key specs

• Format: e-book edition of a twentieth-century literary novel
• Series: New York Review Books Classics, a reissue line for out-of-catalogue literary fiction
• Structure: straight narrative prose, no illustrations or reference apparatus
• Length: novel-length, comfortably read over a week or two
• Reads best on: any Kindle — a 6-inch base model is fully sufficient

What it does well

The reason to single out a book like this in a device roundup is that it represents the workload a Kindle is actually optimised for. There is no layout to preserve, no figure to zoom, no answer key to flip to. Text reflows, the page turns disappear into the background, and the device does its job invisibly. The NYRB Classics presentation also matters: this is a line whose whole editorial purpose is pairing a neglected novel with a serious introduction and clean typography, and an e-book edition preserves the text itself even if it loses some of the physical edition’s charm. For anyone deciding between a 6-inch and a 7-inch model, this is the category that proves the 6-inch is not a compromise.

Pros

• Pure reflowable prose — the ideal e-ink workload
• Works perfectly on the cheapest Kindle in the lineup
• A recognised literary classic rather than disposable filler
• Mid-range price for a book you may reread for decades

Cons

• No searchable reference value; it is read once, linearly
• Mid-range pricing for a novel when budget thrillers exist
• Nothing here exploits a larger screen or colour display
• An e-book edition cannot reproduce the physical NYRB edition’s design

How it compares

Against An Honest Review: A Bookish Psychological Thriller, the contrast is price and purpose rather than quality. The thriller is budget-tier and built for momentum; Stoner is mid-range and built for patience. If you are choosing what to load first onto a new Kindle, buy the cheap thriller to test whether you actually enjoy reading on e-ink before committing mid-range money to a slower book. Against My January Duke, the split is genre: both are prose-only and both run fine on a 6-inch screen, so the decision is purely what you feel like reading.

7. An Honest Review: A Bookish Psychological Thriller – Best Cheap Page-Turner

This suits the reader who wants to find out whether they actually like reading on an e-ink screen without spending much to do it. It is a standalone psychological thriller with a bookish premise — the listing frames it around books and reviewing — and it sits at the budget tier, which makes it a sensible first purchase on a new device. It is also the right kind of book to test a Kindle with, because thrillers are built to be read in long unbroken sittings.

Key specs

• Format: e-book edition of a standalone psychological thriller
• Series status: standalone — no prior reading required
• Structure: narrative prose, dialogue-led, no reference apparatus
• Length: novel-length, typically read in a handful of sessions
• Reads best on: any Kindle, including the 6-inch base model

What it does well

Budget thrillers are the best possible first download for a new Kindle, and the reasoning is practical rather than literary. A thriller has short chapters, high forward momentum and low layout complexity, which means it will not expose the weaknesses of a small screen — there are no tables to squash and no diagrams to zoom. It also tells you quickly whether the e-ink experience suits you: if you finish a book like this in three evenings, you will finish hundreds more, and the device has paid for itself. The standalone status matters too, because starting a series on a new device creates an immediate obligation to buy the next four books.

Pros

• Budget price makes it a low-risk first purchase on a new device
• Standalone story with no series commitment
• Dialogue-led pacing suits e-ink perfectly
• Short chapters make it easy to read in fragmented sessions

Cons

• Genre fiction is disposable by design; little reread value
• No reference or study function whatsoever
• Indie presentation means no series ecosystem to fall back on
• If you dislike thrillers, this tells you nothing about other genres

How it compares

Against Stoner, the trade is price against permanence. Stoner is a mid-range literary classic you might reread; this is a budget thriller you will probably pass along mentally and never reopen. Both are equally well served by a cheap Kindle, so the choice is purely about what kind of reader you are. Against My January Duke, the split is genre and length again — a novella versus a full novel — and both are prose-only titles that make a strong case that the base Kindle’s 300 ppi screen is not a compromise for fiction.

8. Energy Revolution System Review: DIY Power Generation Explained – Best for Home Power Curiosity

This suits a reader who is curious about generating their own electricity at home and wants an explanatory overview before spending money on hardware. The listing frames it as a review-and-explanation title rather than an installation manual, and the audience is the homeowner weighing solar, battery storage or small-scale generation against a rising electricity bill. It is a budget-tier read that works as a first pass before you talk to an installer.

Key specs

• Format: e-book edition of an explanatory guide to DIY power generation
• Scope: concepts and systems for home electricity generation, explained in plain language
• Structure: text-led explanation with a review-style framing
• Audience level: beginner — assumes no electrical background
• Reads best on: any Kindle; a 7-inch screen helps if diagrams are included

What it does well

The genuinely useful thing a book like this can do is give you the vocabulary and the order of magnitude before a sales conversation. Understanding the difference between generation capacity and storage capacity, why a kilowatt-hour is the unit that matters on a bill, and why inverter sizing constrains what you can run simultaneously will save you from being talked into an oversized system. A budget e-book is a cheap way to acquire that framing, and because it is explanatory rather than schematic, it reads perfectly well on a small screen. Treat it as orientation, not as an engineering reference: anything involving wiring, grid connection or permits belongs with a licensed electrician and your local regulations.

Pros

• Budget price for an orientation-level overview
• Plain-language explanation suits readers with no electrical background
• Text-led structure reads well on any Kindle screen size
• Useful preparation before requesting installer quotes

Cons

• Not a substitute for professional installation advice or local code
• Self-published explanatory titles vary widely in technical rigour
• Little reference value once you have absorbed the concepts
• Any diagrams will be cramped on a 6-inch panel

How it compares

There is no true like-for-like alternative in this roundup, which is itself informative: this is the only non-fiction title here that is not exam prep, business or craft. Against Review Ready: The Definitive Guide to Acing Photography Portfolio Reviews, the pattern is the same — both are short, budget-tier, single-subject guides that teach a process rather than a body of knowledge, and both are best read once, applied, and kept only for occasional reference. If you are choosing which to load, pick based on which decision is actually in front of you this year.

9. My January Duke (A Rake Review Season 2 novella) – Best Short Regency Romance

This suits a romance reader who wants a complete story in one sitting rather than a multi-book commitment. It is a novella in a Regency romance series, which means it delivers the genre’s pleasures — period setting, titled love interest, a courtship with an obstacle — in a compressed format. It is also a sensible mid-range purchase for anyone who reads romance heavily and wants to keep a device stocked.

Key specs

• Format: e-book edition of a Regency romance novella
• Series: a second-season entry in a continuing series
• Length: novella — typically readable in one or two sessions
• Structure: dialogue-heavy prose, no reference material
• Reads best on: any Kindle; a 6-inch base model is ideal for novella-length reading

What it does well

Novellas are the format e-readers were quietly built for. A hundred-odd pages of dialogue-driven romance has no layout complexity, no figures and no navigation demands, so the device disappears entirely and you simply read. The series structure also works in the format’s favour: buying the next entry takes seconds, and because the instalments are short, the cost per evening of reading stays low even at mid-range pricing. If you read romance as your main genre rather than occasionally, this is the category where a Kindle pays for itself fastest — heavy genre readers are exactly who benefits from a device that holds an entire season in a pocket.

Pros

• Complete story in a single sitting
• Dialogue-heavy prose is ideal for e-ink
• Mid-range price for a full evening of reading
• Part of a series, so there is more if you enjoy it

Cons

• Novella length means less story than the price might suggest
• Series continuity means starting mid-arc can be confusing
• Genre-specific appeal — no crossover value for other readers
• Nothing here benefits from a larger screen or a premium device

How it compares

Against Stoner, the difference is length and register rather than quality: both are prose-only mid-range titles, but a novella asks for one evening where a literary novel asks for two weeks. Against An Honest Review, the trade is budget against mid-range pricing for a shorter book — the thriller gives you more pages per pound, the novella gives you a complete arc in one sitting. For a device decision, all three point the same way: fiction of any kind is fully served by the cheapest Kindle in the lineup.

10. Review Ready: The Definitive Guide to Acing Photography Portfolio Reviews – Best for Photographers Facing a Portfolio Review

This suits a photographer who has a portfolio review coming up — a festival review, a gallery submission, an agency meeting — and wants a process rather than more gear advice. It is a budget-tier guide focused on the craft of presenting and discussing work, which is a genuinely underserved topic: most photography books teach capture and editing, and almost none teach the twenty-minute conversation where careers actually move.

Key specs

• Format: e-book edition of a photography portfolio-review guide
• Scope: preparing, sequencing and presenting a portfolio; handling critique
• Structure: process-led chapters rather than technical instruction
• Audience level: working and semi-professional photographers
• Reads best on: a 7-inch screen or a colour model if the book includes example images

What it does well

The value of a book like this is that it converts an anxiety-inducing event into a checklist. Sequencing a portfolio is the specific skill most photographers lack — deciding what the first image says, what the second one adds, and what the last one leaves the reviewer thinking — and it is a skill that can be taught in text. So can the mechanics: how to open the conversation, how to take notes while someone criticises your work, and how to follow up afterwards. Reading it on a Kindle before a review is a sensible use of the device, though if the title leans on example images you will want a larger screen, since photography examples suffer most from a small monochrome panel.

Pros

• Addresses an underserved topic rather than repeating camera technique
• Budget price for a process guide you can apply immediately
• Short enough to read in the week before a review
• Text-led structure suits e-ink well

Cons

• Any example photographs lose impact on a monochrome e-ink screen
• Self-published process guides vary in depth
• Limited value once your review is behind you
• Assumes you already have a body of work to sequence

How it compares

The nearest structural match here is Energy Revolution System Review: both are short, budget-tier guides that teach a process rather than a body of knowledge, and both are read once and applied. Against the exam-prep titles, the difference in device requirements is the point — process guides and prose are fine on a 6-inch screen, while anything with example images, drug tables or question sets pushes you up the Kindle range. If you are buying a device primarily for
