Nice video. But it still backs up Microsoft's claims and I don't think Microsoft is being conservative in its rating. That was only a couple inches of water for 20 minutes. Like I said previously it is rated at 1m for 30 minutes, that's based on actual testing. Also, like DroidUser42 said, swimming changes the dynamics. Bottom line - Don't swim or shower with it. However, normal hand washing and being out in the rain should not be a problem.
