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.
