just wondering... whom actually needs i5/i7 on a "notebook"?!
Who needs really powerful machines, well, get a desktop or something similar!
I know, I know... Don't feed the trolls...
Who needs it in a notebook? Well, for that matter, who needs a Core i5/i7 in a "desktop"? Well? Get a workstation or something similar!
For that matter, who needs a Core 2 Duo in a notebook? Just get an Atom. If you need more power, just get a desktop!
Among other reasons, some people like to have ONLY a notebook, and want it to be reasonably powerful. My last two notebooks, when purchased, were each the most powerful machine in my house.
That said, I now have a powerful PC (sadly, Windows-based, and OS X doesn't want to hack onto it nicely,) so my next notebook will likely be a MacBook Air.
Although the just-released (or more specifically, the yet-to-be-released i5/i7) iMacs are looking very inviting. I may even be up for selling my high-end desktop to get one.
As for SATA-3 and USB 3? *VERY* doubtful, as SATA-3 (or, more properly, "SATA 6Gb/s") just came out, and USB 3 won't be officially out for a little longer. Not to mention that support for both won't be in Intel chipsets until late 2010 at the absolute earliest (and Intel recently implied it won't be until 2011.) Apple won't throw in third-party chipsets to support them unnecessarily in a laptop. I mean, I'd love just to see eSATA 3Gb/s in the next MBP.
