I've got a Dell XPS 400 and 600, quite possibly the best pc's I've ever owned. I was looking at the M class for a while now, definitely need to get a few new XPS systems when I finally decide to part with the two I have now. I feel like the guy in the Subaru commercial where he doesn't want to trade the old car in for a better new one. I don't care what anyone says, XPS systems are awesome. Although the Lenovo desktop I just saw looks like it could be a close competitor for me. Even so, definitely getting at least one new XPS system by the Fall.
