So what would be the difference between a fad toy and a classic toy like the Rubik's cube? The amount of time it survives in the market as a popular item and how many people like it?

They don't require skill because fidget spinners are evidently supposed to be an object that just looks cool, is fun to grab and takes your mind off of anxiety-inducing stuff for some moments, even. Hence my "it mostly appealed to aspies" comment from before, but that's just how I see it.

I would say they're more like pocket kinetic sculptures, that are simple enough to be mass produced in different designs. I don't think kinetic sculptures, such as the desk kind, are a fad. Fidget spinners got quickly forgotten and are therefore categorized as such.
