The question this second-generation Samsung tablet is trying to answer is not "How much better can it get?" The Samsung Galaxy Tab 2 10.1 stops at how much. It feels safe pretending there's no such thing as a third-generation iPad.
Under different circumstances, the second-generation Galaxy Tab 10.1 would've been a disappointment. It still is, in a way - especially if you expected a substantial upgrade of the original. This duty however falls on another member of the Samsung tablet lineup.
