Why are so many surprised? Its no different from the leaked video/pictures so by now you should have come to terms with it. As much as i would have preferred a reduced bezel for the extra screen real estate, it doesn't factor into whether i purchase it or not.
That's fine and dandy.
But for others, it was only recently that the leaks became validated -- semi-confirmed, if you will. It's also recently that the leaked photographs gave a clear picture of the Nexus 7.
Come to terms with it? I guess. The iPhone 5 was leaked early and when it became official, people still voiced their disappointments and concerns. Nothing wrong with that. "Don't act surprise" is not exactly a good argument...

You've got it backwards. Those things are there to allow for additional bezel.
Explain, please? Do you mean Google/Asus wanted more bezel, but didn't know how to give it more bezel and their only solution to add bezel was to throw in cameras, dual-speakers, etc?
