Apple and IntelWell, Apple have decided to go Intel. And it looks like they're going x86. They will, apparently, immediately make available a $999 Intel Mac to developers, and a preview of software allowing development for both platforms. Microsoft have said they plan to produce Office for the new platform. Shares in both companies (Apple and Intel) fell on announcement.
UPDATE: Yep, it's x86.
My original ramble about this is here.
