That's neat!

I've been looking at getting an e-reader in the last few days, and the Xteink X4 is one of the ones I considered. I think it's probably too small for my intended use, but it's cool that people are tinkering with it like this.

I got one around december/january this year. I don't know your use case, for me it is okay in terms of size for reading. I do read a lot on my phone, on my laptop, on a larger e-reader.
