I hauled my old desktop out of the basement and installed Ubuntu 8.10 on it. Pretty slick operating system. I had trouble getting the wireless connection going until I popped in a different (cheaper) brand of PCI wireless card. Ubuntu detected the new one right off. Anyone who is slightly curious about Linux should check out Ubuntu. It's my only exposure so far but it seems fairly easy. I've got this desktop set up to dual-boot either Ubuntu or XP.
