Yet another mac vote. It just works. Period.

My office and my household have used macs for years. At least 2 dozen machines involved over time. Only one (the one I'm using now) came out of the box as a lemon instead of an Apple, and this is where the service shines through. Apple has by far the best service available. No talking to India. Knowlegable techs. Various other hardware problems over the years, like dead hard drives or cd players have been repaired/replaced without a hitch.

Anything I need a PC for I can do in Parallels and the performance is more than satisfactory.
