Hi, I currently own a low end Core 2 Duo MacBook. However, I've just completed college and no longer require the portability of a MacBook. Therefore I'm considering an offer to trade it for a 20" Core Duo iMac with dedicated graphics card (x1600), superdrive and larger hard drive. MacBook Specs (first one on the left) http://support.apple.com/specs/macbook/macbook_mid_2007.html iMac Specs (the 20" model) http://support.apple.com/specs/imac/iMac_Early_2006.html I'm unsure whether I should accept the offer since the warranty for this iMac has already expired while the warranty for my MacBook runs for another 4 months (and also the option of extending it via applecare). In addition, I'm worried that the Core Duo processor would perform considerably worse than the Core 2 Duo, given the same clock speed at 2.0ghz. Are my concerns justified?
