I like my first-gen Paperwhite, though I wish it was faster… page turns seem a tad slow, and active content games are impossible to play. But the backlight is great.
I buy most of my books from Amazon because I like syncing across devices (I read on Android sometimes as well). But I use Calibre to remove DRM from every Amazon book I buy as a backup…just in case Amazon ever does decide to wipe my library, I’ll just sideload or even get an EPub reader.
