Hey Nate!
My house is still only a 1 Mac house. We currently have 2 Ubuntu boxes and 1 XP box. I am seriously considering buying 2 more new Macs for X-Mas to replace 2 of these for the wife and kids. For myself, I am still on the fence. I am impressed, but I really want a full tower with expandability but Mac Pro's are damn expensive. I may keep using Ubuntu Gutsy myself, which in itself is pretty damn impressive. But I guess that would be a whole new thread :-)
