Don't make me a filing clerk
Computers should help us, but it's so easy to find ourselves marching to their tune, not ours.
The app culture is great, but it's hard to remember more than a clutch of 7 or so at a time. Smartphones should be, well, smart. What we need is apps that will suggest themselves to us in response to our requests.
That's why the search engine as a single point of discovery is so seductively useful: our needs come first. We ask "what movies are on tonight?" and get a decent answer. Nobody should have to say "what app shall I start to get an answer to a movie question?" -- but that's what your smartphone makes you do now.
Both Android and iPhone have nods to the solution: Siri on iPhone and Android's "intents". But there's a way to go yet.
