This is a simple consideration... my dads CD burner once broke, had he not had a warrenty they would've charged him 290 dollars to install a new drive. This should basically tell you Apples products, while supposedly good, are simply to expensive to maintain in the long haul. Add to that the fact Vista is coming out an your ideas concerning OS X make little practical sense. Why not wait awhile for a Leopard VS Vista comparison? Anyway I would certainly not pay for a Macintosh computer, they are far from perfect when hardware like a burner costs 300 to replace.
