I just replaced my mba (problem with the one I bought a few days ago) and used time machine to bring all of my stuff over. I noticed that my user name folder is 14 gb! A number not to scoff at with the SSD limited space. When I looked at each individual folder within the user name folder, it added up to 5 gb (my mp3s). What gives? I have installed a few applications (half life 2, ms office), but not really all that much. P.S. I'm really new to OSX.
