Cross posting me comment from CNX:

Lemme clarify something about the earlier comments I had. If we see this device as a start to liberate the world of e-readers, it could be a very good effort. If it goes well, I would appreciate it very much. But as a device to use as a real e-reader daily, nope it isn’t.

If the efforts of Open Touch people lead us into an open e-reader ecosystem, it makes all sense that the first open hardware e-reader doesn’t catch many eyes. Perfect is achieved step by step. It doesn’t come for granted for free. However, going for ESP32-S3 still would be a valid criticism.
