Total count is 729GB but that includes, everything in iTunes, Games, Apps, Music, Video, Movies, TV SHows, etc etc. How does everyone manage this, because right now I have everything on one external hard drive, but it is getting hard to manage. I just ordered a MBA 13" with the 256GB but I think I am only going to transfer stuff I watch listen to and use each day. I seem to spend hours fighting this thing each week, and just when I thought I was organized I find something else. How is everyone managing theirs?
