I just bought a macbook (it hasn't even arrived yet) from Macmall.com. My local Apple store told me they will upgrade me to the new macbook. Here's the catch, I will lose the $75 rebate from Macmall.com plus I have to drive about 2 hrs round trip to get to the Apple store. Do you think the new macbook is worth the $75 and the drive? I currently have on the way a macbook with 2.2ghz processor, 120gb hdd, 1 gb ram. Thanks.
