THE HALLMARK of the cellular revolution is the ability to do so many things on the go. Smartphones have given an entirely new meaning to being mobile.
In this sense, being mobile doesn't just mean checking bank accounts or sending an e mail from a phone. On a more basic level, it means doing these (and so many other things) without being tethered to a stationary device. Not so long ago, however, simply doing some of these things on a desktop computer was considered liberating.
The changes we see and are benefiting from have much less to do with any particular device, such as a cellular phone or a PC, than they do with the evolution of a particular technology. the technology is the ability to convey data and signals over a wireless transmission.
