Mobile devices are changing the way people access the Web, and it is no longer safe to say that a specific device or set of devices will be used to access content. One user may have a small screen, another a big screen, and yet another somewhere in-between. Also, device capabilities may vary between mobile devices, with many now supporting gestures, voice commands, and a variety of gadgets.
