Let's try with an error level analysis: http://fotoforensics.com/analysis.php?id=77d17ed4af33e85e1c5...

The black square on the left of the Apple icon looks too dark, like if someone had backed out what was there. Suspicious.

A similar screen appears in many places, for example: http://windows.microsoft.com/en-US/windows/desktops

But I couldn't find an exact match: http://www.google.com/search?hl=en&tbo=d&tbs=sbi:AMh...

The images that I found have a dark blue background image in the place of the Apple icon, so it looks like that really someone had erased that part of the image. And the icon above the Apple icon doesn't appear in any of the other images, so it is probably fake too.
