Awesome video!! One of the most interesting I have ever seen, the human side to the OS is also very important.
As a direct comment to Jenny Lam, I do photography here in Spain, and would love to send you a picture I took and photoshopped not long ago, I think it really works with the natural, fresh and clean feeling you are putting into Vista. I am completely in love with the work you guys are doing with the UI, and would be so glad to send you some photos and maybe be some help to you in finding a good background.
I don't really know how this blogging works, but if you are interested in seeing some of my photographs, please email me at firstname.lastname@example.org.
