Apple would now have to compete against Dell and Gateway, etc. when it comes to hardware. Intel (and or AMD) is always increasing speeds with their chips. Apple would now be forced to "keep up", meaning they would have to incrementally update their product lines. That means that the previous top-of-the-line gets bumped down, and so on. This is OK if you have the sales volume of a Dell. But with Apple's market share, excess inventory can kill you.
Also, Apple would have to compete on price. They'd have to sell their top-of-the-line PowerMac at around $2300 with monitor. The current dual-1.42 goes for $2700 w/o monitor. And the bottom of the line PowerMac would have to be priced at $1000 or so.
Moving to x86 architecture would have to be a last minute desparation move only. They'll stick with the PPC for the long haul.
