So let's see now...
A modern-day cell phone (such as a typical BlackBerry) is now good for:
* Music & videos
* E-Mail & Internet access
* Instant messaging (IM) and chat services
* Satellite navigation
* Social networking
* Document management and/or viewing
* Beating your neighbor over the head!
Oh yeah - some of them make phone calls too!
