I use a first generation Nook from Barnes and Noble. I have only 3rd party books on it purchased from publishers that make ebooks available without DRM. (O'Reilly, Manning, Pragmatic Programmers, Sitepoint) These are all backed-up up on my Dropbox account, so even if they hit the bit bucket, it would be straight-forward to restore them. This works well for me. And, of course, gutenberg.org rocks my world with classic books available in epub.
