When I first saw this iPhone Case, with built-in battery and a light on the back for assisting with low light camera shots, I thought it was genius. The concept certainly is genius. You get double the battery life from something that doubles as a case and still fits in the iPhone dock. A light for the camera is a nice to have and the whole package adds almost no additional weight to the iPhone. As Nate later pointed out, this is not entirely perfect. The case currently covers both the microphone and speaker on the iPhone, which doesn't render them unusable, but certainly reduces their effectiveness. Hopefully when this arrives in the US market, it takes this shortcoming into effect because it's certainly something many iPhone users could benefit from. The video shows a good demonstration of the case and how it works.
