What's your e-reader of choice, /lit/? I'm in the market for one and can't really tell from normal reviews which ones will be most suitable for my purposes:

>3M Library compatible (all of them seem to support it)
>able to access my Google Books stash (none of them seem to have that app?)
>able to upload my illicitly acquired ebooks at will

Right now I read my ebooks on a tiny phone. Is e-ink still a thing or might I as well just get a normal tablet?
