Underwhelmed with the 60D - is it me, or did I get a dud?

This was the typical kit lens, and it was the one my friend has. She seems happy with it and I didn't notice this issue with her camera.

But I am thinking of returning it and trying the other kit with the 18-135 lens. I'm totally willing to invest in better lenses in the long term but want to know that the basic camera at least works for me.

As for the opening as I walk issue, am I the only one who is bugged by this? Do I have a "loose" lens?
