Most recent device is a galaxy S II, flashed to cm10. I've also got an HP touchpad I have been using android on more often since cm10 has been available on it.
My last device was a Samsung Galaxy Nexus (Verizon, boooooooooooo). I'm currently trying to decide between the Microsoft Surface and a Nexus 7 or 10. So maybe this contest will make that decision a bit easier.
