If you were stranded on an island with one app, what would it be?

Words with Friends! Then while I'm stuck I can own them at scrabble

 

dead strike...as long as i could get the control updates. with that many levels and cheat codes, i would be in heaven

 

Safari - I can play a variety of games via web app and maybe while on the island there will be a flash plugin for safari released that I can download to play flash games
