The time goes up with the number of buttons, AIR, *even with experienced users*. It takes a decision to pick which button, and even though it's a very fast one, it's still an extra load. With no choice, that's gone. I strongly prefer multibutton mice. Even on my Macs, as soon as they got USB so they didn't cost extra. On OS X there's rich right-button support. But it is demonstrable that both 1 button is quicker, and is all you need. Now, of course, multitouch is rendering all this moot... -- Liam Proven ?
