I think the general public is fine, it's the tech enthusiast community (no doubt fueled by the tech press, which has to keep printing something to stay in business) keeps expecting Apple to make original iPhone/iPad level reveals every single year. It's just simply not feasible unless you want them to keep throwing crap at a wall every year to see what sticks. People forget how long it was between the iPod and iPhone, and iPhone and iPad, with the intervening years being gradual improvements to the existing product lines. Outside of new product categories being created (and we pretty got the main ones covered now), people can't be expected to be wow'ed at every new iPad/iPhone/etc announcement. It's simply not realistic.
