Ummm, I was wondering if my Macbook is normal or not... I received my refurb Macbook on friday morning jan 30th. I didn't get to play with it for the whole day and now I am starting to understand stuff and all that. I found something interesting though... I thought the Alum Macbook 2.0GHz comes with 160GB of hard drvie?? How come mine has only 149.5 GB on the about this Mac info...? Any ideas?? Should I call the apple customer service??
