Ok, so i'm buying a new MBP and I need the power of a 15" - no doubt about it. I'd much rather have a 13" though. The size is more suitable, and they're just altogether more attractive. Is there any way of upgrading the processor to a quad i7? I originally assumed it wouldn't be possible - but i've just noticed that the mac mini (which comes with a dual i5 as standard) can be upgraded to quad i7 if you get the dual drive model with lion server OS... This makes me think that the i5 dual, i7 dual and i7 quad probably have the same pin layout? But do they all run on the same voltage? Any help is appreciated.
