I havent ridden one, but it looks like just 1/2 a T-board to me. Not really one I'd be interested in trying for sure.
PointSurfBaja- I'd have to highly disagree. What you seem to be describing is a Freebord, which is not a gimmick at all. And the guy who invented it as his masters thesus for industrial design from Stanford, had a very clear understanding of the dynamics of snowboarding. That board was not created to bite off the skateboard, it simply offers a ride for snowboarders who want to get as close as they can to snowboarding in the summertime and longboards just dont cut it.
I could go on about how the 2 extra wheels are actually replicating the petex base of a snowboard (giving you free directional movement, like a snowboard) and how the 4 edge wheels act as the metal edges (or 'rail'), but if ur interested, Discover Channel does a better job explaining it.

Granted, the ones you probably saw back in the days WERE barely functional monsters and absolute disasters to try to maneuver properly... but that's the trial and error of creating a new product. The first oldskool burton snowboards sucked to ride at first too. Freebord figured it out over the years, and their product is awesome these days.
(some good downhill)
I know, cuz I used to ride for them. I thought it was a gimmick at first too and I could barely stand on the thing when I first got it. And after giving up a couple times, I started to catch on and some better models were released.
I'm just sayin you gotta give things a chance sometimes before you write them off as crap (which is hard sometimes, as there really is a lot of crap out there). The snow/skate industry is pretty cutthroat, which is a real bummer as it was open minded innovation that it was established on in the first place.
