I find the TouchPad completely useful. One feature that I found that the Lenovo driver did not have enabled is the Momentum feature. With that I can "throw" the cursor across the screen then "catch" it by touching the TP surface then finish my selection. It's not quite as fast as a mouse but it's close. Besides it's much more entertaining.
Still can't get two finger scroll to work as I'd like it. ( I use "Two Finger Scroll" instead of UltraNav's two finger scroll) I am using the "Chiralmotion" to do scrolling without having to put the cursor onto the scroll bar.
I really like the tap to select. You have to develop a VERY delicate touch. Accidental selections do happen but not frequently enough to eliminate the use of the TouchPad.
I cut slivers of electrical tape maybe .05 of an inch to border the TouchPad. That way I can orient my hand without taking my eyes off my work.
I really like the ThinkPad TouchPad. It's what sold me on my T400. The extra three buttons are very useful. If I enable the TouchStick I can assign different functions to the three buttons. I use the middle button to open items in their own window.
Incidentally, in regards to the sensitivity setting. I've found that the setting really tempers the deeper taps used to select rather than surface sensitivity. Doesn't make sense to me how this hypersensitivity can't modulated. Once I got used to it the hypersensitivity is part of the light feel to cursor control. But it would be good to attenuate somewhat.
