With the new touchpad, the trackpoint is useless because it badly positioned.
The trick is to use the multitouch pad like in a mac and forget about the trackpoint. It is actually not bad, you got pinch to zoom, two finger scroll, etc. Actually is better than the trackpoint sometimes.
That being said, I will change it for a W541/T541 ultranav touchpad asap. But not sure if I will keep it. Getting used to the pinch-to-zoom.
As a general rule, physical buttons and total lack of multi-touch support seem to go hand-in-hand with good ol' quality... but even that is not a foolproof rule.
