The G2 is finally more out in the open and as we had all predicted it looks great. Next to it’s predecessor the G1 it appears to have a much more refined and smooth design. The screen of the G2 is, as you can see in the image above, much bigger than that of the G1. Despite being slightly smaller it is more for the package pound for pound. The G2 has a smaller frame with a bigger screen, optical mouse, definitely a much more powerful internal system, and just better feel in hand. It was designed to give the user much more usability than bulk. Not putting down the G1, but the G2 simply exceeds it in pretty much every way but being the first Android powered device.
