Well, we all have come a long way, the latest phones being introduced are a far cry from the hefty two-handed jobs of the first mobile devices and their purpose is now also a far cry from an emergency. The latest phones being marketed by the big purveyors of such devices are designed to make it easier not to make a call but rather to post your latest updates to the web to social media sites or to upload videos and photos to those sites.
What is this all about? In my view, one word: CONVERGENCE. Convergence of media, convergence of communications. This is to cellphones what VOICE is to your computer desktop. Going forward, maybe not immediately, the concept of the desktop phone will be going away. Instead, VOICE communication (what we used to call a phone call) will be just another application on your computer, just like spreadsheets and word processing. Because, look at it, on your cell phone, VOICE is already just another application. And look at what we call these things now. First they were Mobile Phones, then Cellular Phones, then Cell Phones, then SmartPhones and now just Mobile Devices.
