As far as dealing with legibility, it has pretty high resolution, so you can write small if you'd like. You can also zoom in and out to write larger if you'd like.

I use it for reading and note taking. It's helpful to jot something down quickly or to take more in-depth notes. You can also install Android apps on there too, so I use Firefox to browse the web (reading articles on Wikipedia, doing research into software products) and sync that with my phone to easily pass data between them.
