I was at the Apple Store today and sent home some CineBench benchmarks of a 1.83GHz MacBook there- it's a great machine. Super fast, but the black ones... they all looked like someone ate potato chips and spread all the grease over the keyboards! That matte finish + black color is just a grease attractor. Here are the benchmarks + specs (I know they aren't extremely fair but it's just for comparison)!
