Resurrecting this thread as with my thumb messed up, I've been searching for something to kill time I usually spend playing video games, so I recycled my old 3g Nano and got an 8 GB Touch.
I picked up the Canabalt app (
CANABALT) which has good music and is dead simple and entertaining.
Also bought Homerun Battle 3D which I think is like the game mentioned above. Between this and the Canabalt game, I have plenty of time-killers for when I'm in the doctor's (or physical therapist's) office.
Got the Kindle app. I love my Kindle, it's a nice extension of it especially for when killing time in grocery lines, etc.
Using Twitterific for Twitter and the Facebook app.
Any other suggestions, especially for games/productivity? Any good free tower defense games?
