I think that creation of global online operating system is at hand. Google is already working on it - if you have all your tools online, why need for OS installation on your device? It will be merely a terminal, an access point to a global online system. This idea gives me chills, really.
If you ask about the next part of IT industry which is going to blossom - I would say interactive shopping. More and more vendors all over the world go online, with their shops becoming merely showcases and main operations done online via any device.
If it is raining outside and I don't want to go out - I can order pizza, a new umbrella and a gift for my GF with several clicks on my tablet. And watch Netflix while all of this is delivered. Why go to the shop under the rain?
