I got both at work - I hate the Mac.
As a physical product, Mac is high quality. The material etc.
What people are missing is that Mac is mostly marketing. If I install Mac OS on an Intel based PC, is it a Mac or a PC? Mac users overpay to be a part of a 'cult'. After Mac embraced Intel architecture, the whole comparison become more or less irrelevant.
If I was to buy a computer for an intelligent person who wants to get as much done as possible, I'd buy a PC. If I was to buy a computer for someone who's seriously technically challenged, I'd buy a Mac.
