So long as I can buy a Mac from Apple that runs OSX, or whatever they may call it in the future, I couldn't care less what's inside. If they maintain the standards they have kept up to this point, they could have hamsters swimming in monkey excrement and I wouldn't care, so long as it did its job.
And I don't see why it should make a negative difference to anyone, if Apple, as they say they will (I can say to myself tehre is no reason to doubt this) port everything to X86 chips.
Would anyone say no to a dual 4ghz G<insertnumberhere> Powermac?
I didn't think so.
As for the look, nothin' wrong with the brushed aluminium
Wouldn't supprise me to see a new, sleeker looking box though. With little to no hint htere's an Intel in there. So. Go Apple, for having the balls to switch to Intel
