Apple has been getting all sorts of special treatment from Intel ever since the switch, it seems... Intel must have had some particular reason that they really wanted to hook up with Apple, which I think would transcend current profits.
I posted that when the whole Intel/Apple story started: At that time Intel got their ass spanked by AMD, and all their chips were used for where tired, sad old Dell computers doing boring old things.
Intel chips inside a Macintosh do things that are ahead of anything else. Intel employees don't give a damn whether Dell uses Intel or AMD (apart from the sales people, and bean counters and shareholders obviously care). However, the fact that Apple uses Intel and not AMD is _very_ important to the employees and for company morale. Every time they see a Macintosh, they can be _proud_ that their chips are inside.
