"Fads" are only un-useful when you don't understand them. But once you go over the edge from rejection to application, the fad state desists and you end up with a useful, cutting edge tool. There are very few fads which persist long unless they are understood and used. So I would say that the "fad"-gadget'ization of our technology world is a subjectively-borne reality. It doesn't matter if you don't understand it - some do. That's why its out there in the first place: someone had a use for it.
