The above acronym spells out Mobile Messaging Device. A potentially but unofficial new title and more appropriate name for cell phones. The 'cell phones' is effectively, dead. In function and given name.
The smart phones provided by Rim, Apple, Google and Nokia don't simply make calls. They're smart. Full access to the internet, video, text all in one. All in one sleek plastic, in some cases metal, case. Touchscreen is the new black, but it has many drawbacks. Screens are still in many cases haptic at best. Buttons are a clear alternative.
Phones are used as storage devices and not only tools, essential to daily life now. With all the tasks one can preform on them phone isn't nearly fitting any longer.
