From the first statement of wired.com review, I see that Google Nexus 7 from Asus is not the only one which got 9, Apple iPad also got 9 which is manufactured by Apple. But on 7-inch tablet it is the only one which got 9.
Size does matter. Nexus 7 is indeed Google Nexus tablet but since it is smaller than iPad, there are some limitations for fast performance and for fun activity such as game. For certain game, view is everything, smaller size leads to smaller feature and graphics detail. There are so many preceding 7-inch tablet such as view pad which performs well on general utility except game, so Nexus-7 is not something surprising other than for gaming.
