Depends on what you want to settle for. Its harder to get hardware and software for the MAC. As you pointed out, theres enough out there so that your not so much limited in what you can do, its more just a question of how you'll have to do it. i.e. you can do NAV, but only if you want to deal with the inadequacies of route66. On paper, the mac looks real nice and can do all the same things, to me it comes down to the usability, I just don't see being able to do all the stuff that I do now with my PC and still be able to drive the car.
