Just after showing us the LiveSound promo video, where Sony Ericsson was able to show us the features of their new accessory in under a minute without any craziness and rather simply got to the chase, the company has now followed up with the Sony LiveDock promo video. The Sony Ericsson LiveDock enables you to charge your phone while connecting video out, USB keyboard/mouse, and much more. This new and simple promo video from Sony Ericsson does a fantastic job of telling you everything you need to know about this device, something that Sony tends to struggle with when it comes to their marketing.
