I got a kobo clara bw and a xteink x4 that I gave to my kid. Im quite happy with the kobo, it’s a much better experience for reading imo despite not having buttons. The touch screen is usable after all. I started dumping things into epub format, for example lyrics/chords, things that I want to read, etc. chatgpt is quite helpful with formatting epub files.
I considered buying an X4 for the portability (and to be honest installing and tinkering with crosspoint sounds fun).
But the kobo can fit in my jeans pocket and is about the size of a normal paperback page. I feel like the X4 would be too small and might be frustrating.
