What I was saying, Rand, is that I did not understand what you are talking about when you said "needing a keystroke to get a right-click." I've been on Mac since 2005 and my mice (mouses?) always had a right-click. The latest incarnation I am currently using has it as well, plus scrolling, both up-down and left-right, by swiping a finger across the mouse (just like we use it for iPhones and iPads these days). Rather natural movements and no need to clean the wheel periodically.
