Well, the cat's out of the bag - Jobs has confirmed in his WWDC keynote speech that the first Intel-based Mac will be shipping next June, with the lineup transitioned by June 2007. The demos on stage have been on OS X running on a 3.6GHz P4.

And 10.5 will be known as "Leopard".
 
 
 
 
 
 
Well, it is C|Net, but they're running a story confirming that it is indeed Transitive's work behind Rosetta.
Yay.

I'd seen some Xbench scores posted (PPC code being emulated on one of the Apple x86 development boxes), and the results were not disappointing. Somewhat retarded, certainly, but not horrible, and averaging out to about the same ballpark as my current PowerBook, which is fast enough to keep me employed.

The tidbit I found particularly interesting is that system calls and official API's will fall through to native code; these are not emulated. So those Xbench CPU scores, being fully self-contained, don't reflect what "real world" use will be like...it may actually be downright snappy. Encouraging stuff.

This is all pretty much moot for me, since about 95% of everything I do involves either the OS-bundled apps, or Adobe who've pledged OS X86 support. Bring it on.
