There was someone I read semi-regularly who pointed out that Apple could lose money on the MacMini and still stay out in front. Why? Apparantly, Apple has a large cash surplus. If they're willing to lose $1billion subsidising the MacMini, they'll find out if such a relatively cheap device will sell in quantity. If it does, they've made a considerable dent in the Wintel market. If not, well, it was an experiment anyway.
