The IBM chips were working fine up until the spring, IBM was supposed to of developed dual 3 ghz chips and a G5 chip by that time and they failed so Apple simply moved along. Good idea too, macs will be able to have more power in their processors for cheaper price and they can dual boot. When you break it down, Microsoft loses. They just sell Windows Software, and because this transition should boost Macs a bit and take some space from PC's, microsoft loses some ground. Good, because Microsoft sucks and it screws over it's own customers. It's a clue when users of it's own Software are making fun of Bill Gates and the company. And for the record people, Apple IBM chips are NOT the equilavent of the Pentium 4 chips. The G5 1.8 ghz is the equilavent of a Pentium 4 3.6 ghz.
