Virtual PC turns a powerful mac into a crippled pc. It's an emulator and can never be as good as the real thing...I've tried it before and said screw it and just built a pc, it too darn slow....for about the same price as the software

Unless you just HAVE to have virtual pc I'd get an actual PC. The only thing it's really good enough for is wordprocessing, and if that's what you want to do (pc wise) get Office X for the mac...great program.
