This. When I use my work laptop, I find myself pressing the spacebar constantly. edit: instead of "clicking"

There is at least a whole line up of models from Lenovo. But for keyboards there is currently only tex.com.tw that sells new keyboards with track point.

As an old user of thinkpads for years, on a Macbook the trackpad is as much under your thumb as the trackpoint is under your index finger and I find the trackpad far more accurate and less strain to use. In fact, my work-at-home setup is macbook pro, open face so i can use the keyboard+trackpad but external monitor so my posture isn't terrible.
