I wonder, what's the next hot thing made by apple? Whats going to be the next iPod/iPhone/iPad...? How long will apple be able to continue without a new, unique and hot-selling thing? I know, that apple has a ton of money, but the apple tv and the iWatch are not something major. And i don't see them on the front of interesting stuff (cloud, containers, virtual reality, social networks). How long can they increase the screen of the iphone each year? how long can they let the app store like it was, well, since forever...?
