I am TRYING to move from WIn to MAC, which if you just look at the OS, it is an easy decision. But I am a loyal Thinkpad user which is exceptionally good and sturdy hardware with the little red nipple thingee which is so much better than any track pad, even the greatly improved one on my new MCP. Taking my hands off the keyboard to go to the track pad was driving me crazy, why can't I assign what is considered the "right click" to a keyboard command? You can't, and that was driving me crazy! Then I found KM and it is very possible it saved a marriage between me and MAC. Now if i need a right mouse click, I don't have to put two fingers on the track pad anymore, I just slide one thumb down to the command key and the other thumb to the space bar and voila, right click nirvana baby! Mr. Jobs should send the guy who made program a commission as I just ordered the new 17" MacBook Pro. I it was not for KM I would be getting a new T500 Thinkpad instead. This is a great program.
