XP Reloaded. I'm hoping the Linux folks who worked on the matrix special effects sue the pants on Microsoft for that.

BTW... Did you see the part in XP Reloaded, when Mr. Torvalds, I mean Neo, dives deep into the guts of the matrix and kills Bill Gates, I mean Elrond, err, I mean Agent smith and then it all restarts again -- and only the command line remains?
