What's up with the sudden stagnancy in production and a more visible iterative line-up nearly everywhere?

As far as I know, there really isn't that much going on in the world of tech, is there? Everything's getting faster and better, of course, but where is that "I'm definitely getting this for Christmas" factor in a new product? Have we reached some sort of a temporary threshold in tech?
