I used nothing but PCs from 1992 until two years ago when I bought a Mac for the studio. It's _never_ crashed, unlike the machine it replaced. I now have 3 Macs and am working towards the time that the remaining PCs can be retired.

My take on this is simple - if you want to constantly fiddle with a system in an attempt to make it work better, buy a PC. If you want to actually do something useful, head for the Apple store.
