Booked, bothered, and buttonless
Open Book Touch: open-source e-reader
The tiny open e-reader is here, and readers are already fighting over buttons, screen size, and bedtime vibes
TLDR: Open Book Touch is a new tiny open-source e-reader built for pure reading, not apps or distractions. Readers love the idea, but the comments instantly turned into a mini-drama over missing page-turn buttons, the small screen, and whether simplicity is freedom or compromise.
A new open-source e-reader called Open Book Touch has officially arrived, and the community reaction is basically: "Finally!" followed immediately by "...but why no buttons?" The pitch is deliciously simple: a tiny pocket-sized device made just for reading, with no buzzing apps, no social feeds, and no internet rabbit holes. It opens straight to your book, lets you load files yourself, and keeps the whole design open for tinkerers who want to modify it. For people exhausted by distraction machines, this thing is being treated like a tiny rebellion.
But the comments? That’s where the real page-turner begins. One camp is swooning over the clean, minimal look and the honesty of the project knowing exactly what it is. Another camp is already mourning the missing physical page-turn buttons like they’ve lost an old friend. Several readers basically declared the old Kindle Oasis the breakup ex they still think about. Others nitpicked the small 4.26-inch screen, saying they want something bigger, while one commenter politely-but-pointedly asked for a truly distraction-free mode with even less clutter on screen.
And then there’s the hacker energy: if the case files are public, can fans just add the buttons themselves? That idea gave the whole thread a fun DIY chaos vibe. The mood overall is admiring but demanding: people love the anti-distraction dream, yet they’re already casting it in the comments as either a pocket-reading masterpiece or an almost-perfect gadget with one very dramatic flaw.
