There are already more than 150 million consumer smartphones in use in the U.S., and that number is expected to grow to more than 200 million by 2017. The figures for tablets are equally impressive, with the current 132 million expected to grow to more than 190 million by 2017. With 39 percent of the U.S. workforce already working in mobile environments for a significant part of their week, this is also a revolution.
