Perhaps the reason Dreamcast refuses to die is because of its 'underdog' status. Or maybe people have just realised that yes, indeed, it's pretty darn cool. I'm quite happy with mine, especially for the price.
Apparently, so I've heard, it's not terribly difficult to make off-site backups of the games. Allegedly.
Cheers,

who bought Ecco The Dolphin the other week and reckons it's kinda cool (if only because Tom Baker did the narration...)
