I've owned Kindles for 13 years. I've written a whole post raving about them. A couple of months ago I picked up an Xteink x4, a 4.3-inch e-reader that clips onto your iPhone's MagSafe, runs on an ESP32, and has a hacker community around it. I was in a supermarket queue, reading on it, when I realized I'd never have pulled out a Kindle or a paperback for three minutes of waiting. The Xteink had changed when I read without me deciding to change anything.

Using all three side by side — a paperback, a Kindle, this tiny thing — is what got me writing this. The differences aren't screens vs paper. They're about what each one makes easy, what it makes hard, and how those frictions shape the way you read without you noticing.

Paperback, Kindle, and Xteink x4 — three reading devices

Getting In, Staying In

The real difference between these three isn't size. It's how much stands between you and reading.

A paperback needs a bag. It needs a decision in the morning: am I going to read today? You pack it with intent. You read on the balcony, in bed, at a cafe you went to specifically with a book. You don't end up reading by accident. And once you're in, the book demands the most of you. No backlight, so you need the right conditions. No dictionary, so you figure words out from context or break your flow. But the pages are fixed. You feel progress in your left hand getting heavier. When I finished The Devil's Alternative a few months ago, the last fifty pages physically thinned between my fingers. That sensation doesn't exist on a screen.

My most memorable reading this year was all on paperbacks, and I don't think the books were better. I was just more relaxed while reading them. The object slowed me down. There's no notification that could reach me through it. No other book, a tap away. Just the one I brought, and whatever pace the pages set. A paperback makes you settle into its rhythm because there is no other rhythm available.

A Kindle is slim enough to toss into any bag without planning for it. When I flew home for semester breaks, I'd carry my Kindle instead of choosing one book, because I could have twenty queued up. That shift from pre-commitment to on-demand changed my reading more than I expected. E-books are easier to get and usually cheaper, so I'd download a new one the moment I got curious. I went from finishing books to sampling them. Part of committing to a long book is knowing it's long and deciding to stay anyway. The Kindle makes that invisible. A 200-page novella weighs the same as a 900-page epic. A percentage bar replaces the feel of pages.

The Xteink lives in my cargo pocket. If I can take my phone anywhere, I can take the Xteink. I've been reading in places I never used to: waiting for friends, on a short cab ride, in a supermarket queue. Three-to-five-minute stretches that used to be phone time. Forty, maybe fifty words on a 4.3-inch screen. You turn pages constantly. It feels closer to scrolling than sitting with a book, except the content is a book. That sounds bad, but it works for the right material. A novella on a long bus ride. A chapter of something you're already halfway through. It falls apart when the writing needs room. Ulysses on a 4.3-inch screen would be miserable. So would anything with footnotes or diagrams or long paragraphs you need to sit inside.

The Xteink x4 is supposed to attach to MagSafe but only on the iPhone Pro Max or Plus. On a smaller iPhone it clips on reversed, and the camera bump means it never quite sits flat making it unreliable.

The paperback asks you to plan around reading. The Kindle asks you to carry it along. The Xteink just comes with you.

Everything Around the Reading

I didn't expect to care about this part as much as I do.

I love Penguin Classics covers. The uniqueness of a book cover plays a bigger role than it should in how much I enjoy owning it. Then there's the shelf, the collection growing over years. But the real thing is annotating with a pencil. Writing notes in the margins, underlining, then handing that copy to someone. I used to buy used books from Books by Weight in college. Finding someone else's notes in them felt like being handed a map of another person's attention. What they chose to underline, what they pushed back against in the margins, what they skipped entirely. You're not just reading the book anymore. You're reading someone else reading the book. No e-reader lets you do that.

There's also the social surface. A book cover faces outward in public. People see what you're reading. Sometimes they comment on it. I was reading Dune at a cafe in Mumbai during a book meet when an older woman walked up and told me she loved the series. We spoke for a while about the books, the characters she remembered. That conversation doesn't happen if I'm holding a Kindle. The Kindle hides what you're reading. Nobody knows if it's Dostoevsky or a guilty-pleasure airport novel. But it gives you something the paperback can't: persistence. I went back to a book I'd read a decade ago and all my highlights were still there, synced to Goodreads. A paperback gives you richer annotation the day you read it. A Kindle gives you annotations you can still find ten years later without being physically near the book.

Paperback, Kindle, and Xteink x4 side by side, each showing the cover of the book being read

All three can show the cover of what you're reading. Only one faces the room.

The Xteink has none of this. No notes, no covers, no signal. Most people don't even register you're reading. I've come to find that freeing. There's no performance in it, no shelf to curate, no cover to show off. And when I want to read something I'd rather not advertise on a train, the Xteink is the only one of the three that lets me. The paperback shows the cover. The Kindle at least shows you're reading. The Xteink shows nothing.

What Form Factor Teaches You

I work in consumer tech. I think about what makes people pick a device up, put it down, come back the next day. Using all three side by side taught me something I wouldn't have gotten from analytics.

Each one doesn't just compete with the other two. It competes with whatever else could fill that moment. The Kindle competes with Netflix on the couch, the in-flight entertainment, the twenty-minute YouTube video before sleep. The Xteink competes with the short-form content you'd doomscroll through in a five-minute gap. The paperback competes with the decision to just not bring anything. Each one has to win a different fight.

That changes how you think about form factor. It's easy to treat it as a spec — screen size, battery — and optimize within those numbers. But those numbers don't tell you which moment the device gets invited into. No backlight cuts out bedtime reading. Screen size decides what content works. And input method decides whether you stay. The Xteink has physical buttons. On the Kindle, you tap, nothing happens, you tap again, and two pages turn at once. The delay is in milliseconds, but I didn't notice it until I used the Xteink's buttons for a week and came back. A reliable input disappears. An unreliable one reminds you, every few pages, that you're using a device. None of these are specs you weigh against each other. They decide which moments in someone's day the product is allowed into.

At work, we went with a neckwear form factor for our device. Some people would rather have it in other shapes, and they're not wrong. A MagSafe attachment like Plaud records phone calls, but you have to keep it out and start it yourself. It's deliberate, like packing a paperback. Our neckwear sits near your face and captures audio all day without you thinking about it. You don't start it, you don't pull it out, you don't put it back. It's just there. Neither form factor is wrong. But each one assumes a different relationship with the person wearing it: one asks for a conscious decision every time, the other asks for trust once.

The same logic applies to reading. The Xteink answered a question nobody was asking: what about the five-minute gap? It didn't win by being better than the Kindle. It won by being small enough to be there when the Kindle wasn't.

Closing Thoughts

I've been reading more this year than the last two years. I set myself a goal of 25 classic novels, and for the first time it feels possible. Not because I tried harder. Because the gaps filled in. The paperback is for slow weekend afternoons on the balcony. The Kindle is for the half hour before sleep. The Xteink is for lunch breaks I used to spend scrolling my phone. I didn't plan that. The shapes decided it for me.

What I actually want is a 5-inch pocketable e-reader with a backlight and physical buttons. Something that collapses the Kindle and the Xteink into one device. It doesn't exist yet, and it might never. If it does, the paperback will still have its place. The covers, the pencil, the shelf. Some things you can't compress into a pocket.
