"The overall design is mostly unchanged from the previous model, though the specs indicate it gained a little weight likely thanks to the slightly larger 4870 mAh battery and PixelSnap magnets. I think the design is a nice alternative to the other Android flagships, so it is good to see Google iterating on what works. "
