As it happens, Intel's was not the only alternative chip design that Apple had explored for the Mac. An executive close to Sony said that last year Mr. Jobs met in California with both Nobuyuki Idei, then the chairman and chief executive of the Japanese consumer electronics firm, and with Kenichi Kutaragi, the creator of the Sony PlayStation.
Mr. Kutaragi tried to interest Mr. Jobs in adopting the Cell chip, which is being developed by I.B.M. for use in the coming PlayStation 3, in exchange for access to certain Sony technologies. Mr. Jobs rejected the idea, telling Mr. Kutaragi that he was disappointed with the Cell design, which he believes will be even less effective than the PowerPC.
Now that Mr. Jobs has broken with I.B.M., however, Apple is free to pursue a potentially intriguing consumer electronics strategy with Intel.
Intel has been looking for ways to get its chips into devices that can compete with game consoles as living-room entertainment hubs. In fact, all three next-generation video game machines made by Microsoft, Nintendo and Sony are based on I.B.M. chips. And analysts say that both Microsoft's Xbox 360 and the Sony PlayStation 3, scheduled to arrive next spring, will be positioned as home media hubs in addition to being video game machines - and priced far lower than the Intel-powered, Windows Media Center PC's that are also aimed at the living room.
Should the new consoles find wide acceptance as broad-based entertainment engines, Intel will need to respond - and one attractive alternative would be an inexpensive Macintosh Mini based on an Intel processor, able to run the vast library of PC games.
Before he can set his sights on that new market, Mr. Jobs faces the task of shoring up his base, his customers and developers. On Monday, he made the case to the software designers who must be willing to rewrite their software for the new Macintel world.
Early indications are that he made a convincing presentation.
"The reason people buy Mac is the software, and I think the real fun is yet to come," said Scott Love, the president of AquaMinds, a software concern in Palo Alto that sells a Macintosh program called NoteTaker used by writers, researchers and students. "We'll be able to develop a program that will just work on both I.B.M. and Intel-based computers."
