I have found that the Apple Support is far and away better than a lot of the others out there.
Dell has gone downhill, rapidly, for a number of years now. Take a look at the poll, can't remember who commissioned it, regarding customer satisfaction for Support. Apple came out on top, again.

I deal with Dell on a daily basis, and am not impressed with their support. Their Business support is "lightly" better than their Consumer support, which "reverse blows"

The main reason the Dell was half the price of the Mac, cheap and nasty stuff inside it. That, and the fact that it is half as good as the iBook.
Check the specs on that discontinued machine! Celeron, small, slow HD, shared video, disgusting reviews. Dell suckers you in with the $300 rebates.
