One thing that I have not heard mentioned here yet is cost. I think that the main advantage of the Intel Centrino solution will be that the parts cost to build an 802.11 (a,b,g) laptop will be less due to the integration. Fewer parts means less cost. If apple decides to include Airport (Extreme) on all laptops then they would probably want to put it on the motherboard to save the costs of the connectors and packaging of the cards. It would cost even less it the 802.11 circuitry was built into a chip that they already have there anyway. Sherman
