Ipod touch..
Movies, games, music
There really are some great very unique games due to the tilt and touch controls. Mostly puzzle games play best, lots of tower defence games, a lot of cool ports of java and flash games, the 1st person shooters are not great, as well as most of the racing titles.
But games like doodle jump, bubble head, icopter, flight control, zen bound, Eliss (best games ever!!) and Galcon (srsly a GOOD game!!!) are all great games. Most run around .99cents-$1.99 :thumbup:
Honest I have not played the Ps3 in months due to all the "unique games" the iPhone/itouch offers

(and I'm a die hard gamer

... Might be a phase? But really look at some YouTube reviews of the games above and see if you might like them?
Plus movies, plus music.. All should keep you awake. Just keep it away from the Mrs. Because she will want to take it!
