Heh. That thing is pretty sweet. I would get it too, but for a novelty item $199 is way too high.
Can it even be used as a hard drive? If you have an old IBM mainframe around the house, maybe. But I dunno how you would link it up via SATA or IDE. Wait, what did we have in the '80's? ATA and P-ATA? lol. I don't even think those would work.
