Really loving my new Google Nexus S. The battery life leaves aa little to be desired but, Im liking it very much. Ive owned 4 androids and this is the best Ive owned out of a HTC Desire, Motorola Defy, a Samsung Apollo and the Nexus S. All I need to do now is root it. Ive seen a battery pack on the internet, it comes with a backcase that looks kind of bulkyAnyone bought this or even stronger battery for theirs??? Worth getting???
