Apple iMac 24in

The near-total lack of upgradability is an annoyance, particularly given how easy hardware upgrades are on virtually all other PC systems. It's slightly lacking as a media centre too - Apple's Front Row software has fewer features than Windows Media Center, and the lack of an internal TV tuner hampers the iMac's ability to replace your TV. But if you can live without the TV tuner and want a PC that actively resists tampering and upgrading, not to mention runs both OS X and Windows, the iMac is an attractive package.
