Good grief, this article is such pandering crap. People didn't dislike xbone because it was "too new, too scary", it seemed like an awful product, and part of that was the seriously poorly handled PR fiasco created by MS.
I like how these pop psychologists have sound bites for anything they ever want to validate as true- if the market positively reacts to something new, then it's because "people are adventurous, they like to try new things!", or if not, then it's "people don't like change, ho hum". There just aren't any blanket rules because what's black today might be white tomorrow.
I think timing and luck factor a lot into how well a new product is received, but it's also true that some things are just veritable turds, i.e. no amount of good timing of good luck can or will help them.
