The article says 600,000 smart phone users and that there will be 8 millions in a few years, including tablets. That is really far off.
there are around 3.2 million DoD employees, active, reserve, and civilian. Lets add a bunch of contractors and say an even 4 million. Very few people get black berries most get regular cellular phone, however even the cheapest cell phones have some "smart" qualifications.
there is no way there are even close to 600,000 using black berries, android or apple devices.
that 8 million is even more of a joke are they planning to slap a tablet on to every large weapon around?
