1. When Apple upgrades to Intel what is the big deal about that? More speed?
Eh...
Pretty cool actually that people indeed consider this transition no big deal. I seriously hope that in the future everyone will think about it that way.
But, to inform you:
The Intel switch is such a big deal to us Mac-followers that this action has absolutely littered all Mac -rumors, -news, -info sites (and forums) for the past 3 months (about that long ago Steve confirmed it).
In short, Apple has always used CPUs which "speak a different language" than Intel's: the current Mac-CPUs are called PPC (PowerPC). So for software to be able to use that CPU they also have to speak "Mac (PPC) language".
Now that Apple has gone over to Intel for their future CPUs, all software must be altered (or completely re-written) to be able to use the Intel CPU, or will run in "emulation mode", which is slower.
This Intel CPU is also used in Windows compatible computers, so in future Macs the CPU will be the same as in the dreaded WinTel boxes.... That is a bitter pill to take.
Why did Apple do it?
Yep: primarily SPEED.
The current "high-end" Mac CPU is a G5. This processor is too large, i.e. too hot to get into a nice PowerBook. The PowerBook is therefore "still" on the older G4. Not bad for Mac minis and iBooks, but a bit too slow for Pro Macs, like the PowerBook.
The future of PPC looks bad according to Steve, and Intel's future with the x86 CPU seems to be great. So in order to get speed, stock and reduced size Apple went to "the other side".
