The internet of stuff is next!
A lot of the building blocks are in place, personally I think Arduino is a really big component that is driving the revolution and Kickstarter is providing a surprisingly good platform for funding it. However there's still a few missing components. One of the goals of LTE is to power this new network, but existing carrier business models don't seem appropriate. As a consumer I'm really not interested in paying $20 (or more!) a month for each my fridge, and toaster, and television, and door to be connected. Light Squared was a promising push in the right direction, which unfortunately failed.
Along the same lines of networking though, I think there's a lot of really good opportunities for low end hardware. Qualcomm dominates the market in LTE chipsets, but good luck getting access to the developer stuff as an indie user. API's tying all these components together will be essential.
