My last experience with a MacBook Pro, my friend used the keyboard 99% of the time. The few occasions he used the touchpad, it was almost entirely composed of 1+2+3+4 finger gestures for switching between programs/tabe, scrolling, and so on. This actually became a selling point for me, and why I'm considering a MacBook for my next laptop.
And at this point, I need to learn to stop feeding the trolls. But I thought my point would contribute to the discussion anyhow. :-)
then why would you go to an OS that mandates the use of the mouse??
