What is a Mobile Device?
Typically, a mobile device is a cell phone. You'll typically have a screen, buttons numbered 0-9, and a few minor navigation buttons. All in all, you don't have a lot of controls. Certainly for most phones you don't have a full keyboard or mouse, or even a very large screen. When you get beyond the interface, you'll find that the processor and memory are equally thin. Currently my cell phone brags a massive 972 KB of memory, which is nothing when I compare it to the 300 GB I use on my computer.
