Ah Ha! I think I figured out, or possibly figured out, the "blem." I can't photograph it and it's very hard to see (I just caught it by accident), but if I hold the body sideways, so that light is reflecting off of it, the part of the logo where it says "mini" reflects differently - there is almost a halo around it, like it was added later or didn't adhere the same way as the rest of the logo. I wonder if anyone else's looks like it or if I'm nuts.
ETA: I think I am nuts, but I can't find anything else that might even remotely be wrong with it. Blems Rule!
