There is some obvious unfairness in this, in the Microsoft bloke being obviously trained in how to do this, but I don’t think anyone’s saying it’s a scientific experiment, and the Windows Phone looks very impressive doing this.
If I might add one quip about the objective of the challenge, I don’t see why uploading the image would be something that would need to be done instantly. Clearly, the thing must be getting to the camera quickly, and quickly snapping a photo. The uploading (to Twitter, Facebook, or wherever) can take its time, as I see it.
Still, the Windows Phone looks great.
