Having recently worked on implementing a video solution that deploys across hundreds of sites, it's shockingly hard to find out how to play video on Android browsers. This is a bigger issue than I think most geeks realize. Most iOS devices I can download an app for all the popular video sites plus see their videos in the browser, whereas with Android I can rarely do either.
The tech's not that new. There's been Tegra2 tablets available for months.
I'm guessing the software has something to do with it as well though, so you might see jumps similar to Android upgrades (visible here if you compare Xoom and Atrix) on old iPads when the new one comes out (assuming it has a new iOS rev too).

The Xoom loads pages, on average, in about a quarter of the time of the iPad.
