And the winner is... not us :(

Update: We've added a video of some of the lucky Tab 10.1, Galaxy S II and Samsung TV winners after the jump!

While a few lucky Americans waited to have their Galaxy Tab 10.1's updated with Samsung's TouchWiz UX, we were lined up among hundreds of eager British shoppers waiting to get their hands on the European version before anyone else. Like the Tab 10.1 currenty on sale in the US, it's rocking Android 3.1, however the European version comes with TouchWiz out of the box. We've taken a closer look at TouchWiz on the Tab in our sneak peek and hands-on features, so be sure to check them out.

Early adopters were treated to a selection of drinks and delicious miniature snacks courtesy of Samsung, and there was also the chance to win Galaxy S II phones, Galaxy Tab 10.1's and £1500 (~$2450) value Samsung TV's via the Samsung Tab Grabber. We used the Tab Grabber, but all we grabbed was a plastic egg containing a raffle ticket that didn't win us anything :(

Check out our tour of the event after the jump, where you'll find photos and videos of people having fun and winning expensive Samsung gear.
