These threads make me understand why Apple keeps its iPhone / iPod Touch tech specs under wraps (or at least tries to).
Any single individual spec doesn't matter. Overall, these new MBP systems are faster, as any review is and will continue to show. And these faster machines come with better screens at a better price point. Period.
Complaining that your 13 inch MBP only comes with SATA I, is the same as complaining that it only comes with a 2.53ghz processor and not a 2.8.
Would it be faster if it was 2.8? Yes. And the distinction is just as arbitrary as SATA I vs SATA II. In fact its worse because for many of Intel's chips they are the same chip, just artificially throttled at different speedswhy not be up in arms about that?
Is the old 13 uMB faster, overall, than the new 13 MBP? All the reviews I've read say no. Faster, more I/O and better screen, and better battery life at a lower price point. What's not to love?
Again, there are all sorts of ways to make a machine faster, and Apple has chosen not too. Is it for battery reasons, cost reasons, engineering reasons that the geniuses in this forum don't understand, or simply artificial marketing decisions in an effort to help sell product? Could be any, or all of the above. Apple makes decisions based on those criteria all the time. Every computer company does.
If Apple starts charging more for less of a computer, then that is something to get up in arms about. But pick a taskany computing taskwhether it be surfing the web to mixing video, and it seems you can buy a computer today for less money, that will accomplish that task faster than the computer you could buy a week ago.
Thats progress.
A computer is more than any individual spec. This discussion has devolved into a common problem in digital camera reviews called pixel peeping: Where people care more about the specs of the camera than the art they can make with it.
Macs are for people who want to create. If you want to geek out on specs, you'll get a lot more options and satisfaction in the commodity PC market.
If you want make something, I'd suggest looking at one of the new MBPs. They are faster than before and more affordable. They seem like a really good deal.
