In my mind, the Dreamcast and the SNES are the only two contenders for the title of Greatest Console of All Time.
The day Sega re-releases the Dreamcast--perhaps in a new form-factor with integrated broadband and a hard drive--will be a glorious day indeed.
For now, I must manage with my Xbox 360 which, though it is in many ways the spiritual descendant of the Dreamcast, is but a shadow of the DC's greatness.
You guys have fun over there with your Metal Gear Solid 2s, Tekkens, Gran Turismos, etc. I'll be over here playing Shenmue, MvC2, PowerStone, SF Rush 2049, Phantasy Star Online, 24-hour Le Mans and the definitive console version of Quake 3 Arena.
Alas, poor Dreamcast, you did not deserve your fate.
