Trackpoints IMHO suck hard, simply because you need a lot of fine motor control to precisely operate them, the texture is bad, and a single "purring cat on closed lid" event can be enough to permanently stain the screen.
There are people on this world who legitimately have physical/neurological issues with fine motor control. The latter one just happens to include myself.
Apple's touchpad is far superior - it allows for really precise gestures as well as high speed coarse gestures, just varied by the speed of moving.
