In this story of Apple going from PPC to x86 architecture, it is pretty obvious to me that it is not so much a choice or advantage of one architecture versus the other, but clearly a business related decision.
IBM relations with Apple were probably not that great since IBM could not deliver what the G5 roadmap they had promised Apple since the first G5.
Freescale (the worldwide embedded processor leader) is obviously only looking at making embedded chips, and is very successful at it! PPC chips are found already everywhere in many systems, planes, cars, networking devices, etc... The latest 7448 is a marvel of engineering, consuming 10W at 1,7Ghz and offering CPU power way beyond any other chip on the market using 10W or lower.
I think that the success of the move of Apple to Intel will solely be determined by if Intel can make the roadmap they sold to Apple for their x86 chip.
I also believe that such a move by Apple is going to have to be justified by hard number to the shareholders, and if you look at how antsy are the shareholders are to make a lot of money now with Apple since the iPod, my guess is that the move to Intel better show some major costs savings for Apple, because I don't believe they will be happy with the explanation: "Intel promised us better chips", because after all Intel just trashed the Pentium 4 architecture and 4-5 year long project, a few billions dolllar in the process... So their enginneering capability is not that supperior. Intel shines by its manufacturing and agressive marketing, not its designs (which BTW is often not even done by Intel itself!).
The future will be interesting
