That's interesting, I just wrote the Senior Editor of Macworld to ask him about the product and he states in his email "...I do have a Comfort Wave keyboard, as it turns out, and can confirm that it ships with Mac software -- Logitech Control Center -- that lets you program all of the media keys and such for their Mac equivalents. The Windows and Alt keys are clearly mapped as Command (Apple) and Opt for Mac users, so the Comfort Wave doesn't discriminate for Mac users."
Conflicting stories :-\
I am considering buying one. Perhaps I will have to go into a store and ask to see the contents of the box first.
