Dragon Diction was pretty crap for me... it got about 90% of what i said, about 50% of what my mother said and about 10% of what my dad said when we all three read the same prompt into the phone... the 10% or so it didnt get on me was enough to make it lack any sense at all...
i try to keep all the games off mine but the two im guilty of are scrabble and Paper Football 3D. actual apps are Alarm Clock (make sure you get one that will run even if you dont have the app up!) RedLaser, TwitVid, Crackle, a couple of radio stations, a couple of banks, the norms of facebook and twitter, IMDB and Showtimes and i dont know if it really counts as an app or not but ibooks.
oh, and yelp... but i dont know if they'd have that for OZ or not...?
