How did I miss this??

I am sure that this is a mock-up by somebody (because we all know how secretive Apple can be), but this would be an awesome idea. I am in the market for one of the new aluminum Macbooks, and in my hunt for consumer reviews, I found this photo on Flickr. Apple believes that there is no market for such a device. I am not sure if there would be or not if it remained in the tablet form, but if it were a convertible touch screen (that is, a keyboard that would fold away), there would be a demand for such a netbook.

What do you guys think? Have you seen this photo before?--it is about a year old now. If you're an Apple fan like I am, what do you think something like this would do for the company?
