But dont underestimate Apple, a great power base of intelligent minds.... My personal guess is they are floating in a sea of sharks right now.....
Uh, first of all, OS X has been running on Intel processors for the past 5 years, and for almost 15 years before that when it was NeXT.
Second, as was reported by C|Net and The Wall Street Journal several days before the official announcement of the switch to Intel processors, Apple is going to start moving the consumer computers over to Intel before the pro computers—thus they will be starting "from the bottom up". As C|Net and The Wall Street Journal were right about the switch, it is safe to say they are right about the stratagem Apple will use when the switch begins.
The Mac Mini will assumably be the first to get the Intel Inside make over, followed by the eMac, iMac, iBook, PowerBook, and lastly the PowerMac in mid to late 07 when the transition is nearly complete.
As far as the emulation goes; at the Keynote Jobs demonstrated both Adobe Photoshop and Microsoft Office running through the Rosetta emulation layer. On a SINGLE P4 chip running at 3.6 GHz the emulation ran at a respectable speed. By the time Intel Macs finally start coming out expect the Rosetta technology to have been enhanced, and expect the chips included in the systems to be much more advanced than the P4. Also the Pro systems will be dual systems, and I doubt Rosetta would be made in such a way that it can't take advantage of SMP.
As far as there being no updates to PPC only apps...why would companies just completely drop their support for PPC Macs? 100 percent of their user base is on PPC Macs and will be for several years to come if historical trends involving Apple computers continue. Mac users hold onto their machines for a very long time, and even though OS X has been out for 5 years now and OS 9 development has been stopped, there is still a large base of installed OS 9 machines out there running in professional environments. Don't expect this to change over night just because Apple's switched to Intel.
