Thanks for the tip on Hacker's keyboard!

Re: backups, on my wife's Nexus, contacts/calendar are taken care of by DAVdroid, some photos/videos through ownCloud instant upload, but I also installed rsync4android from the Play store and configured an rsync backup should can manually trigger (but rarely does) of the rest of the user files.

I still like the idea of an incremental and ideally automated backup of as much as possible... though I've never really had to restore anything. (That may change soon, as she lost her Nexus outside the apartment a couple days ago and hit hasn't resurfaced!)

Anyways, thanks for the tips!
