I see everything moving to a ChromeOS-like model, with HTML+JS and WebGL for graphics-heavy things. If not those technologies in particular, something equivalent. Essentially the consumer OS will be reduced to being a platform for a browser (I use "browser" loosely here -- I consider iOS to be an app browser in this sense). The OS will disappear from visibility. To make this work you'll need a lot more standardization on APIs and data formats (because in the future consumers won't touch "files" anymore). I also think that's coming. Finally, I see the server/client sides being even more divorced from each other. Clients will become dumber (single-purpose) and servers will become smarter (multi-purpose), and both will be much more connected.
