Look at other photos in the same set - you'll see that the dust spots are gone.
I'm normally very obsessive about cleaning my lenses, but that particular morning, I woke up at 6AM and immediately went to the Taj, so as to avoid the huge crowds. After taking a few shots, I realized that my lens was dusty, and I kicked myself, then used my LensPen to clean the lenses.
I was hardly going to try and clean the sensor in the field, heh.
Also, look at my other photosets. You'll see that there're no dust spots - that's because I took the time to clean the lenses, first.
The bottom line is that I don't have a chronic sensor dust problem. Given that the OP is experiencing fringing & sensor dust issues, I wonder if his M9 body is somehow twisted out of true so that it's not sealing properly.
