What makes a phone smart? Is it the keyboard? Or the operating system that allows you to write memos, surf the web, and manage your calender? Or is it the ability to connect you to certain networks? Well, it's all three. Since the early '90s, mobile phones have been transforming into mini-computers, letting us do things we were once only be able to do from a desktop or laptop. With mobile operating systems and hardware getting more advanced, the line between phone and mobile workstation is about to blur even further.
