The Xteink X3 is a tiny 3.7-inch E-Ink reader that weighs about 58g and is roughly 5.1mm thick, small enough to slip into a pocket and hold in one hand. Its 528×792 screen runs at 259 PPI with no backlight and no touch, so text is sharp and glare-free but you read by ambient light and navigate with buttons and a shake-to-turn gyroscope. The rear magnet and metal rings let it stick to a phone as a secondary E-Ink display. The open-source Developer Edition unlocks firmware access for tinkerers, but it runs only the official Xteink app, not third-party apps. It suits commuters and developers who want a minimal, hackable reader rather than a full-featured Kindle-style device.
