4" screen and 16MB flash is a joke. Ebooks are small, but not that small. Considering how many used, end of life Kindles there are out there stuck on old easily jailbroken firmware, I don't see why anyone would ever choose this as an alternative. The software for jailbroken Kindles is incredibly mature and at the point of "just works". E-ink technology hasn't progressed much in the past ten years, so you really don't miss out on anything by buying a $30 used one.

Edit: just realized it has micro SD support. So my storage concerns are invalid. It's still incredibly clunky looking though, a 1cm thick device with only a 4" screen sure is something. My eyes probably couldn't handle it even with the largest font.

To be fair, eBooks have just gotten that big in recent years because the publishers are lazy and cram uncompressed embedded fonts into them.

I always strip out embedded fonts from my eBooks with calibre and I have seen books being reduced from 20MB to 400KB. 🤣

This won't make this a good device due to a myriad of other reasons, though.

Yeah, definitely think there are use cases for this (look at how popular the xeink X4 has gotten), but a device smaller in most dimensions than modern smartphones isn't gonna make a good general purpose ereader for many people
