The Sony Ericsson LiveDock is due to launch imminently. As you would expect the dock includes the ability to charge your phone or perhaps use it as a stand to watch videos. It also allows you to launch a specific app automatically from the LiveWare manager application such as a desk clock or photo slideshow.
However, another cool feature is the ability to control your handset via a mouse and keyboard. Rog from SE-First aptly demonstrates this in the video below, where he connects a keyboard and mouse to the dock to control an Xperia ray. This allows you to write text very fast. It’s probably a gimmick more than anything but it’s still cool to watch nonetheless.
