The smaller one doesn't look to compare too well to the Nexus 7 - it costs the same, is marginally heavier and has ads. I guess if you need a lot of support to use a tablet...? The big 8.9" model, on the other hand, is impressive - .84 pounds is extremely light for a screen of that size and resolution. I'm almost skeptical that they're claiming 12 hour battery life on top of that. Did they achieve some kind of battery breakthrough?
