I now have a nice bluetooth keyboard to use with my Android phone, which makes writing/editing large volumes of text reasonably feasible, and the performance of the phone (Galaxy S2) should certainly be up to the job. However, I've not (yet) found Android software that seems comfortable of editing documents in the 50,000 to 100,000 word size range. (And, sadly, Google Drive seems totally incapable of handling these - performance comes to a halt). Has anyone tried actually writing/editing a book on Android? Any experiences or recommendations to share?
