Why not make this transition permanent? (rather oxymoronic I know)
Forget ending the transition, just make Macs that can use either PPC or x86.
Before you say I'm crazy, think about it: as Steve is saying:
1) OSX is fairly cpu agnostic
2) Shops are going to have to live with a double fat universal binary for quite some time.
3) The translator software is put in place, are they going to yank it? Why not expand it to go the other way too?
4) Apple can pick the best CPU for the task at hand, just like any other part.
5) I don't think anyone would be confused, or grieving, or sad, or in shock... but would be the evolution of computers from the revolution company. Steve would be again hailed as a visionary, instead of, "I guess he had to face up to reality"... come on, this is STEVE JOBS we are talking about here. IMPOSSIBLE == POSSIBLE, right?
Now, as is, IBM has ZERO incentive to improve the 970 for Apple.
But there's the what if, a BIG WHAT IF, something cool and new comes out from IBM, or Freescale after the transition is complete? Oops, hey group, let's go back?
IBM made the 970, and it is really good. Why can't they do it again?
A "transition" will scare people into holding out, hurting current sales no matter how many people say it doesn't matter. If it's not a transition, but spun as more of it doesn't matter anymore, then maybe people will think, hey cool, it's just like picking different video cards or something. Mac is great at hiding the complex. Most people in this thread have shown they don't want to worry or even know the details in the machine, just that it works, and it works well.
Nothing new, or different is done in this transition, this isn't Apple's first time at it either. But, making the Mac support 2 different cpu architectures at the same time is really cool, and would clearly put OSX into a category untouchable from that other one.
Downside is the support required, but over time this would just be the standard, and a massive competitive advantage.
Steve, if you can hear me, never end the transition! Long live the transition!
