I've yet to have my device delivered but I played with one in a retail store (why did I preorder then if stores get it before me?).
Anyway, it seems from my time playing with the one in the store that Chrome lacks a major feature in a 7-inch tablet browser... full screen mode. The screen area on a 7-inch tablet is relatively small, you have to optimize UI as much as possible, and keeping the tabs at the top, and the system bar at the bottom is a waste of space in my view, especially in landscape. Ever seen a Samsung Galaxy Tab 7.0 plus/2? With the browser and the status bar, 20% of the screen is lost when surfing online in landscape mode.
The Honeycomb browser has an option of getting rid of the tabs and address bar at the top, with a half-circle of controls you can bring up by sliding from the edge of the side of the screen. Unfortunately, Chrome doesn't seem to have it. Sometimes I wonder if 7-inch tablets should just stay with Android 2.X, which allowed for full screen mode much better. Or maybe Google should make the status bar disappear when using apps, bringing it up by swiping from the bottom, or have an option to make it transparent inside apps.
Anyway, I think Dolphin has the full-screen mode. Opera Mobile is nice, but doesn't have it. Maxthon got it too.
