I’ve got two of the previous version of these (without the volume control, and different media controls) - one of the quiet for my office and a regular for my home.
They collect dust like crazy, but I pretty much swear by them.
Total agreement; they’re the best keyboards that I’ve found, and the internal USB2 hub is sweet. The only drawback, imo, is that the hub should be over on the left side, not the right, to keep plugged-in devices from getting in the way of my mousing hand.
