PCs only have one advantage over Macs; the vast about of smaller programs written by developers. Although the peer-to-peer software is pretty much even now.

I have used PCs for he last 15 years and would swop any day if wasn't a matter of having to buy a Mac software. Hooky copies of PC software seem easy to come across than Mac, not that I'm suggesting anything of the sort but its worth noting for the casual home user (who I personally shouldn't have to pay licence fees for software)
