I'm waiting for the Android port of Emacs to mature. It currently has issues with hardware keyboards and with Tramp. But once it works well, then I'm getting a Nexus 10 and a Logitech K810[1]

Emacs-TRAMP will let me edit files locally so it will work well even if you're in a location with spotty internet.
