MacBook Pro Touch Pad Sensitivity

Is there a way to decrease the sensitivity of the touch pad? In Windoze I was able to set the touch pad so that accidental brushes from your palm while typing didn't affect it. The one on my new MacBook is super sensitive and it's driving me nuts.

under sys pref. >mouse and keyboard >trackpad >ignore accidental input.
it's not the best, but as good as you can get. (as far as i know)

I was afraid someone would say that. I've already set it to avoid accidental input but it isn't any better. was hoping for a new more robust driver with lots of options like I had in windows. A button to turn off the track pad would be awesome. So far I'm not as impressed with the Macbook as I was expecting to be.

I understand that steer mouse is designed for usb mice - but just maybe someone has been able to use or adapt this driver to the touchpad.

Just a suggestion...
