  • Recommended E-reader? [more in comments]
    An Android tablet and the CoolReader app. For me, it's simply the best eReader experience available. It's incredibly customisable. The only downside is it doesn't support PDF or AZW3, both of which can be reformatted to your preferred file type with Calibre anyway. Source: almost 4 years ago
