You're really good at cherry picking, aren't you? Anandtech for the performance numbers, Engadget for battery life numbers. By Anandtech's numbers, the Nexus 10 gets 93% of the battery life of the iPad, even though the Nexus 10 uses a much smaller battery. Between the lighter battery and the grippy back, Google designed a device that can be safely held in one hand, a tradeoff I appreciate.
