They've done some impressive things on the hardware front recently--the Mac Pro redesign and streamlining their MacBook line come to mind--but since the iPhone 4, which had some incredible innovations like the antenna and Retina display, their mobile line has only seen predictable iteration. I expect the iPhone 6 to be a significant deviation in form factor from the iPhone 4/5/5S because Apple is run by smart people who are rarely late to the party.
No doubt. They are still doing great things. But, especially in the case of the smart phone market, the competition is catching up. Or at least coming close enough for a lot of consumers. In order for them to maintain the kind of dominance they are now used to, I think new types of products will be necessary. FWIW I'm not giving up my iPhone anytime soon and would be lost with out my Macbook Air.
