I don't think the technology is dumb at all, quite amazing actually.  But it would be dumb for somebody like me who isn't a musician to buy one and play with it then have it sit around the house.  Even for musicians, it's just kind of a fancy keyboard that looks a heck of a lot harder to learn.  I guess it all depends on the price, but I can't seem to find anything about that on the web.  I was more amazed by the iphone! (but I still don't have one of those either) :(
