Duh'
Since the market for disks and processors does the same thing (ie bigger model for same money), this is a nobrainer... And afaik all computer brands do this (keep price, up specs).
Apple has upped the specs of its three MacBook Pro models while maintaining the previous models' prices. Essentially, the upgrade involves bigger hard drives all round, plus faster CPUs, up either 100MHz or 200MHz, depending on model. The 13in MBP has a choice of Core i5 or Core i7, while the 15in and 17in models are Core i7 …
I hope they've improved the cooling as well. I moved from a 17" dual core 2.66 GHz i7 to a 15" quad core 2.3Ghz i7 and the latter runs much much hotter. Hope the extra hike doesn't result in even more heat - I now get audible fan noise when just watching iPlayer whereas with my old 17" machine I could count on one hand the number of times I'd heard the fan. Looking at the Apple forums, I'm not the only one with this problem on the faster processors.
On the positive side, those Sandy Bridge CPU's are like the provebial fecal matter from a gardening implement. I've never seen the CPU usage go above about 15% in Ableton Live.
