Hands-on Surface video at Microsoft's Windows 8 event in Shanghai
Steven Sinofsky made an appearance at press event in Shanghai announcing Win 8 and Surface. Attendees were allowed access to Surface and Win 8 machines. WPDang.com website has pictures and videos of the event. There are some hands-on videos of Surface at website -- not great quality though. Unfortunately, I don't speak Chinese, so I don't know what impression they got from Surface.
