I can't say whether moving to the x86 platform (and losing those fat profits from their hardware sales) would be good for Apple's business, but I sure as heck would like to see it happen. It should have happened ten years ago. And five. Now it may well be too late for Apple to compete with Microsoft on its own turf, and now Microsoft is busy fighting the Linux hydra. But Apple's strength has always been its software, particularly OS software; it's time they made their best stuff available on the best available platform.
