If it works and you got used to it, it is so great on the integrated display. I got so used to not leaving the home row, I get annoyed when I have to use the arrow keys.

My X220 nipple unfortunately became a little unreliable. Needs calibration often (auto moving cursor) and sometimes one direction works better than others. It's annoying, especially since the touchpad is just unusable.

Any suggestions? Hardware or software issue? Would a new rubber nipple hood thingy help?

Its probably a hardware issue. I worked at IBM and they were very proud of that device that was invented there. They had a little glass display with the hardware broken out and prototypes.

It works with strain gauges[1]. Thats why you can control the speed of the pointer, not just the direction. When you get used to it, its quite effective.

You can pull the rubber nub off and try it, that shouldn't help but it might. If its sticking in a position that isn't "Neutral"

Oddly IBM made a mouse with that nub pointer thing. It worked so much better that any sort of wheel for pointing and scrolling, but I left it when I left IBM many many moons ago.

Thanks. Maybe I get a new keyboard (new nipple) alongside some SSDs for the next 6 years to come.
