According to IDC, mobile workers will number 1.2 billion by the end of 2010--thanks in part to the growth in VoIP technology.

The driving force behind the growth is the emergy markets of Asia/Pacific and the regions use of unified communications (UC) technologies. According to the analysts, the mobile workforces in the U.S. and Europe have peaked. The U.S. is described as having a highly concentrated mobile workforce, but that by 2013 over 75 percent of workers will be described as mobile in some way--that's 129 million people. Compare that to Asia/Pacific figures, and you'll see why IDC is saying the real action won't be in the U.S. By 2013, about 37 percent of Asia/Pacific workers will be described as mobile, and before you say that percentage sounds smaller, it is actually 734.5 million people!
