Since Jobs died, Apple hasn't really created a new product category that none of us knew we wanted.

Jobs died a relatively short time ago; even when he was at Apple, it's not like they created new product categories all that often - maybe every 3–5 years?

I can't help but feel people have expectations which are a little too high.

This. In its 35+ years Apple created - or at least codified - the personal computer, the mp3 player, and the modern smartphone. I think it's closer to a big new product category every 5-10 years, really.
