I have one and I really like it (upgrading from an early Kindle Paperwhite) I find that that the built in e-reader software (which handles epub, pdf, djvu and other common formats) works better than installing standard Android applications for that purpose (although those also work if sometimes a bit sluggishly). In terms of Android apps, I mostly use Libby, as my public library uses that for not only ebooks but e-magazines. I read The Economist and The New Yorker that way, which is nicer than reading it using Libby on my phone as I used to do.
