Most of you who saw my thread about deciding to keep or not keep my MBA will prob ask, so let me get it out of the way. Still waiting to try and exchange for 4gb MBA. Anyways, my current 64 gb only has 25gb of free space. All I have installed is, Facetime Beta, Steam, Team Fortress 2, Day of Defeat Source, Left 4 Dead and Office 2011. TF2 and LFD2 are only 6 gigs each, day of defeat 602MB and Office 2011 1 GB. Thats roughly 14GB. I know the 64 is formatted to 60 and after iLife 2011 pre installed and the OS should leave me at 50gb. But 50-14 isnt 25 GB. Where is my other 11GB or so?
