I just bought a refurbished black macbook 2.4ghz 250 gig for £699. It's black. Is it nice? Didn't see it live. Am buying it for my ex-girlfriend. The other white one 2.4ghz 160 gig sells for £659. Did I get a good bargain? Should I change to the white one? This is because I still can cancel the black one. £40 for additional 90 gigabyte. quick help!
