Well... it is true. Apple just announced that all new Macs will be  
transitioning to Intel processors by the end of 2007. Somebody at IBM  
must have done something to really annoy Stevie.

Apple has apparently been keeping separate builds of Mac OS X on  
Intel processors since the beginning, so the operating system has  
basically already made the move. Now, the problem is dragging along  
the rest of the software. Apple claims that developers who are  
already using Apple's Xcode development environment will be able to  
painlessly make the switch. For others, there's an on-the-fly  
translator that will take PPC code into Intel code.

I think the big push was the fact that Intel has come out with good  
chips for laptops, and IBM wasn't moving the G5 in that direction.   
Powerbooks are Apple's other big profit center, and they can't afford  
to fall behind in that market.

I can see advantages and disadvantages to this, and there are a lot  
of questions that need answering.

The immediate downside is that there are a lot of developers who've  
spent a good deal of time optimizing their programs for the G4 and  
G5. This painstaking optimization can't be translated because the  
architectures of the two families are very different. (Little-endian  
versus big-endian, for example.)

The eventual upside is that it will make translations between Windows  
and Mac OS X easier because many optimizations done for Windows will  
carry over. So, expect to see more Windows-only companies pushing  
their products to the Mac. Also, the Windows emulators should start  
running at close to full speed under Mac OS X.

I think the biggest question in the whole thing is how generic the  
Apple/Intel hardware will be. If Apple produces generic Intel spec  
machines, then they've doomed themselves to being just another  
hardware company competing with Dell and the herd of nameless Chinese  
dwarves who make commodity PCs.

It's a pretty warm day here in Louisville, but Hell did freeze over.
