No, shutterfiend, you don't have a noisy copy. They don't call this lens the coffee grinder for nothing!
I just bought myself a copy of this lens today. I replaced my Sigma 80-400 with it, for medium telephoto zoom.
Although I can clearly hear coffee griding if I press my ear against the lens barrel, I honestly cannot hear the IS while normally aiming with the camera.
The Sigma was clearly audible, both in terms of IS and AF micro motor. In comparison, the 70-200/4IS is a silent lens.
Also, the IS kicks in smoother and slower than in the Sigma and the EF500. Is also shows much less floating of the image compared to the other lenses I have with IS.
Will be taking my first BIF shots tommorow, while on a boat en route to my summer house. Hope the pics of seaguls are sharper and more of them in focus with this lens.
BTW. It's such a small and lightweight lens, it's a joy.
