This makes no sense, what-so-ever. Apple felt a pain when it migrated to PowerPC. It felt pain when it migrated from OS 9 to OS X. I can't imagine Apple just switching chips again. It just seems crazy. What does NOT seem crazy is to provide people with the ability to "move" to a Mac and still have descent Windows functionality without using a slow Virtual PC. People could have the "best" of both world.. a great peice of hardware, a great operating system and something they can use to connect to work with. That makes sense... but a 100% migration move? No sense, what-so-ever.
All these "gaming" machines, Play Station 3, XBox 360, all use PowerPC. If anything, PowerPC is becoming HIP And COOL, and so is Apple w/ the iPod. Now is not the time to produce more "change", but to produce switchers and take advantage of that. That is WHY I believe that any Intel talks are purely base don a compatibility board and nothing more.
