The angle/position the guy is holding the camera vs the angle of the picture is not correct. He is holding the camera much higher than the picture is relative to the macbook.
Not if the photo was cropped before being uploaded onto web. From that photo alone, it is not clear what angle the camera is being held, how high the laptop is and also how far the person actually is from the laptop.
One thing that strikes me is the angle of the screen. It seems to be nearly vertical, presumably so the photographer's face is not captured by isight.
This doesnt mean I think the photo is real, sharing my observations
