Looking for a MBP C2D upgrade from my MBP CD. Aside from the fact that mine is 1.83 vs 2.16, the MBP C2D has more RAM (1gig vs 512) and more HD space (120 vs 80) and DL. I am looking on ebay because I can't buy another edu discount right now. Or could I but one online at the Apple Store anyway? Is it a kind of honors system? Anyway, I was looking at these http://cgi.ebay.com/MacBook-Pro-MA8...QQihZ020QQcategoryZ140065QQrdZ1QQcmdZViewItem http://cgi.ebay.com/Apple-15-4-MacB...QQihZ007QQcategoryZ140065QQrdZ1QQcmdZViewItem Wondering if they are legit. I have been scammed on ebay in buying an Xbox 360 before and was out $400. Should I just go through Apple edu online? Or wait for a refurb C2D?
