With the Commuter case, one small disappointment for me is that the pictures on the Otterbox website make the front look like the same smooth (somewhat reflective) plastic as the back, including the front buttons. I knew the case came with a silicon sleeve, but I thought the outer shell covered the front as well as the back because of those pictures. In reality, the front is just part of the silicone sleeve, so it's a dull, rubbery look. It doesn't look like the smooth/reflective black plastic in their pictures. There is NO shine whatsoever on any of the rubber section (unless maybe you oil it up or something).

Also, on the actual case, there's a seam that runs along the edges -- it looks like a joint between the front and back of the case (although I think it's just part of the mold because it's in both the silicone sleeve and the plastic shell). But in the pictures they smoothed that out so you can't see it.
While this isn't a deal-breaker, the case looks a little cheaper than represented IMO. They definitely spruced up the pics a bit. Compare with my pictures below.
Other than that, it's a nice case. The side buttons are as easy to press as without the case (but the ones below the screen are a little harder). And my thumb isn't flush with the screen whenever I need to slide it along the edges with the case on. That's not really a problem, it just requires a slight adjustment because it's noticeable at first. I didn't notice any sharpness to the top edge as cmathis mentioned.
The case adds to the "solid" feel and classy look of the phone. Only the rubbery front detracts from that somewhat compared with their advertisement. 4 stars out of 5 for what I perceive to be a slight misrepresentation there, but still a nice case.
These aren't the best photos -- my batteries died before I could get more angles, and the ones I took didn't turn out well:
