I really want the macbook air, but i dont know if it will last 3 years ( only going to have it for 3 years then im giving it away). I will downloadd bittorent,adobe flash, microsoft word,google chrome, vlc media player, and windows media player, and problaby like 20 games from the app store, and diablo 3, I only have like 12gigs of music and i am upgrading to lion the most I will have at any 1 point is 20 gigs of music but i usually delete them when im done, my old 5 years old sony vaio has like 160 gigs and its completely full but it is also filled with a bunch of crap i dont need, So I was wondering, would this laptop last me 3 years? or am i better getting a macbook pro. Oh and im also installing antivirus. (Only an indepth answer please, I cant find a real answer for my needs
