Hi everyone. I'm looking to sell my White Macbook (2.4Ghz) I bought in September for school, in order to buy the new 2.0Ghz Aluminum Macbook. I really want the graphic upgrade.. But I've already registered my Whitebook under my name for warranty. Will it be a problem if the Whitebook breaks down and the buyer takes it to the Apple Store? Is there a way to take my name off this product registration? And also, do you think it's a worthy upgrade? Especially since my Macbook is pretty new... Thanks.
