I think Dave Winer will be proven right on this. Apps will die. The web will live. Why? Because of linking. LINK
And perhaps the ease of making mobile-friendly web pages and “responsive web design”, even websites which act just like a native app on the iPhones or Androids of the world — have you seen nytimes.com/chrome/ in a Chrome browser?
Just about the only thing which will stay apps are video games since linking is not (or at least, less) important in a game since games are usually self-contained universes. And even there I might be a little wrong.
