Hi guys, I just got the 128gb model. It says, when I check the info on my hard drive that it has a capacity of "120.47gb" (why?) and has only 106.76gb of available space. I understand that the OS takes up space, along with other programs and such, but how does it go down from 128 to nearly 120? Where does the OS come in? I'm very surprised that, right as I turned it on I only have ~107 gb of space. Can you guys explain this? Thanks for your input. Bender.
