As noted above, 100% is likely to drive you insane. One thing I'm starting to see as an emerging theme is that 100% on the 7D, especially, will drive you nuts. I think those of us that pixel peep in our own homes are running into shock at how much minute amounts of movement are affecting shots that high res when viewed 100%.
The example shots look like their shadows are too harsh or contrast has been jacked through the roof and have some pretty harsh lighting; but sharpness doesn't really seem to be much of an issue in them. I think several have missed focus, but there does appear to be a plane of focus in them.
