I don't have a theory. I was simply stating my experiences with Kinect owners; most of them were teen hipsters. I never said that this was the actual statistic (seeing as I don't even have numeric data to back my opinion).
It was more the hipster bit that I was querying ... the definition (or at least use) appears to have altered a lot in the last couple of years. I think you mean what I'd call a "fashion victim".
