I carry around two phones. Along with an iPhone, I lug around a BlackBerry Bold -- which many call a dinosaur -- for one reason and one reason only: the physical keyboard.
While most have moved to briskly typing on a piece of glass, I still love the feel of real keys. But over the last few years that hasn't been enough to stick with a phone. You know the saga: BlackBerry's software had become so outdated that the masses fled for modern phones with apps and browsers that actually worked.
