Miss? I've never used multi-finger gestures on a touchpad. Mostly because I don't use touchpads. I think that kind of interaction feature came about after I had already written them off as annoying. But it seems like I'd have to significantly remove my focus from the home row to do that - instant disdain.
I just looked it up and it appears as though these gestures you speak of are used for scrolling, swiping, zooming, and alternate clicking just like on a tablet.
I use the alternate button (left mouse button for me) for alternate clicking.
I use the middle button for scrolling.
Swiping, I think is to switch apps? That would be alt-tab.
Zooming is usually some key combination or key in combination with a left or right mouse button drag.
If you don't use the pointer it's probably just a matter of getting used to and tweaking the settings. Make sure to go into the mouse settings and play with both the trackpoint firm-touch, light-touch sensitivity as well as the operating system's pointer speed. Then just practice. I've even gotten to the point where I can do a half decent job playing a FPS with the trackpoint. I wouldn't try to compete in Quake Arena with it, but for casual single player use it's quite alright.
