I was thinking the same thing. Their data, according to the article, indicates that over half of all functions used in Explorer are via the right-click menu and yet they conclude that these items aren't discoverable enough? Bizarre.
I think they're overlooking the fact that it's often a smaller & quicker movement to get to an entry in the right click menu than to mouse up to the toolbar and click there. Fitt's Law applies.
But they aren't eliminating the context menu, no? Right clicking is intuitive for me, but it is not for many people. I speak from my own experiences doing tech support professionally and for family and friends.
