I use an x230 (amazing little machine). I deactivated the touchpad in favor of the trackpoint. I would go nuts if I had to move my hand back and forth in order to move the cursor. If your profession involves a lot of typing, the trackpoint is the pointing device of choice, IMHO.

If you happen to use the trackpoint, I suggest replacing the default rubber piece with a concave one. Here is an example: [0].
