Global processor head count please

Heard at Gartner (in the context of how the world's global infrastructure must scale):  Currently, in the market today, there are about 1 billion computers in use.   There are 2 billion cell phones in the market place and over the next few years, that's expected to climb to 3 billion (many of which will be smartphones).  Today, when all-tolled (including other devices like cars, embedded devices at home, and our wallets and clothes that have processors on or in them), there are about 50 billion "devices" that make use of processors.  That number is expected to climb to 200 billion in the next five years.  How they'll all connect to the Internet and talk to each other (without bringing the network to its knees)?  That may still have to be figured out.
