Yeah, I read that yesterday on DailyTech and Gizmodo.
I wouldn't be suprised, but Macbooks are selling pretty well with the current Intel setup. But, if Apple adopted AMD, it would probably be so all the fanboys can shut up. Look at Dell. If you compare their AMD desktops to its Intel counterpart, the Intel-based machine easily trumps the AMD one. Why? Core 2 Duo, and both computers pretty much cost the same. So you tell me which would be a better deal? An Athlon X2 or a Core 2 Duo?
Relating to the last line in TRDCorolla's post, I agree with what Steve Jobs says. Apple will sell more with their computers running with Intel processors. Intel are more widely known to the general public than IBM is when it comes to microprocessors, because almost everyone uses either Intel or AMD, not IBM.
