We spent some quality time with Samsung this morning at its TouchWiz update event in New York City (you might have seen a tweet or 20), and I got my Galaxy Tab updated as part of the shindig.

We've already done a screenshot preview -- now it's time for our video hands-on. Probably the most important change is the quick-launch tray, which gives you a sort of dock down at the bottom of the screen.

Check out our video above, and stay tuned for more from the London event.
