This is a weird year. Microsoft makes the switch to PPC and Apple does x86. So does that mean both MS and Apple are dead? Apple migrated twice in the past but they're still here. Apple's switching to Intels because Intel can deliver better performance per watt than what IBM can muster within the same time frame. Apple's just doing what's best for their customers aka their bottomline.
By most people's logic having Linux on x86 makes it "dead and irrelevant" seeming Windows makes up the bulk of the desktop. Most people buy Macs because of the OS. The processors shouldnt really matter. Having a stable platform that doesnt have viruses and spyware matters to some people.
