Its funny how everyone is over analyzing the "glares" and "shadows" of these pictures. Well consider this:
Do you know how many light sources there were?
Is there a flash on the Camera?
Is there a window where the sun came in?
Was he/she standing over the product casting another shadow?
What types of shades, bulbs, style of light were used?
i.e. If you go to a basketball court, gym, football stadiums, take a look at your shadow... Its not the same ol' shadow you'll get from being out in the sun.. No not at all in fact there will be 4 shadows.
Oh and as far as "depth", well how much depth do you expect, from an analog "nub"! Note: The screen does have to slide over.
