My biggest complaint is regarding web sites/applications that basically ignore the existence of keyboards. Some of this comes from the UI toolkit that they're using, but it's pretty egregious. For just "brochure" web sites, it's not that big of a deal, but some are really, really bad about tabbing order, or tabbing at all, and certain controls don't work correctly without the mouse/touch.
