I have a Kobo... I don't remember the model name. But the thing I like best about it, is that I never had to sign into anything to use it. (There is a sign-in/create account screen, but this is easily bypassed if you know how to edit an sqlite file.) Once I have an ebook in DRM-free ePub, I just plug it into my computer, copy it over in the file manager, and then just start reading. No Calibre or any other special software needed.
