On paper, it should lose to a Kindle in almost every category. There's no backlight, no touchscreen, no app ecosystem, and the stock software is rough around the edges. Yet somehow this tiny ESP32-powered e-reader has built one of the most passionate communities in tech.

In this video, I take a look at the XTEINK X4, the custom firmware projects that transformed it, and why people have become so obsessed with this quirky little device. From CrossPoint and CrossInk to Sumi and community hubs like readme.club, the story isn't really about DOOM running on an e-reader. It's about what happens when people are free to improve the gadgets they own.

If you enjoy unusual gadgets, DIY projects, abandoned hardware, and communities that keep interesting technology alive long after companies move on, consider subscribing. That's basically what this channel is all about.
