If you compare a mac's peformace with a compariable PC, they usally outperform when loaded with BootCamp and XP. I've really never used a macintosh, but most benchmarks seem to follow this pattern. As for quality, they are very high quality. My Mac Mini is extreamly solid. I worked on Dell's at the hospital, and man, you could hardly plug in the printer(LPT port) without all the ports being bent back into the case, behind the I/O pannel. Talk about cheaply made! I can press on the DVI port on my mini and it doesn't move at all.
