The New York Times provides some details behind Apple's switch to Intel. Of note, IBM was in the dark about the transition until very late in the game.

Several executives close to the last-minute dealings between Apple and I.B.M. said that Mr. Jobs waited until the last moment - 3 p.m. on Friday, June 4 - to inform Big Blue [IBM]. Those executives said that I.B.M. had learned about Apple's negotiations with Intel from news reports and that Apple had not returned phone calls in recent weeks.

IBM claims pricing was the major issue, while Apple insists performance delivery was at the core of the switch.

The New York Times also confirms that Apple has investigated other chips as well. Apple reportedly met with Sony regarding the Cell design but Jobs "was disappointed with the Cell design, which he believes will be even less effective than the PowerPC."
