I went ahead and ordered one. I know how scratch prone the camera strip is, so even if I don't like the case, I want to have something from day one. I really wish Nokia would have made the strip out of something other than the metal they used. Or, if they are sold on that look, maybe have it recessed just a mm or so. As soon as it gets here I'll post a few live shots (without the 900 obviously, I won't have mine until release day).
I just received this case in the mail. Its very similar to the included case with the 800. It's a bit thicker. One big drawback, in my opinion, is that the buttons aren't cutout, but rather have overlays. I'm always skeptical of that, but I know some prefer it.
