I've been using my N810 as sort of an universal communicator for a while now, and for this it has generally served well. The only thing I really miss is Skype video calls.

Numpty Physics is a maemo port of the awesome Crayon Physics puzzle game where you draw objects and play laws of physics to get a ball moving to the end of a track (download):
