You probably hear the term "smartphone" tossed around a lot. But if you've ever wondered exactly what a smartphone is, well, you're not alone. How is a smartphone difference than a cell phones, and what makes it so smart?
In a nutshell, a smartphone is a device that lets you make telephone calls, but also adds in features that, in the past, you would have found only on a personal digital assistant or a computer--such as the ability to send and receive e-mail and edit Office documents, for example.
But, to really understand what a smartphone is (and is not), we should start with a history lesson. In the beginning, there were cell phones and personal digital assistants (or PDAs). Cell phones were used for making calls--and not much else--while PDAs, like the Palm Pilot, were used as personal, portable organizers.
