There's nothing wrong with 'Fat Bastard' suggesting to have a look at the windscooter. Everyone 'good at water-board sports' will most probably be rather disasppointed about a 4-wheeled boards sensation. Expecting a sports car and getting a bulldozer
There's a short paper about the PRINCIPAL difference between 2-wheelers and 4-wheelers, which is independent of brand or special design. It contains a few facts, that the 4-wheeled riders never tell:

Yes, you can't ride an inlined board backwards. But do you really believe we stop, pick it up, turn it around by hand an then start again? Hahahaha. Dream on!
I personally turn it around with the front foot in the time my kite needs to turn into the new direction. If I don't turn it around by a hop. I've never found this a problem. I have the impression, that most of the time, 2 additional wheels are needed to compensate a lack of imagination.
If windscooters don't rock, then kitesurfboards don't rock either.
The only thing that rocks is a tiny-wheeled offroad skateboardlet (of 1960's technology) with a damn cool design painted on it (and the letters MBS of course), right?
4 wheelers are either damn heavy OR have too small wheels. That's a fact!
They are either made for high speed (egg shox provisory) OR they turn well. Another fact.
Besides the lack of surfing feeling. Yet another fact.
