I have used a Logitech Trackman Wheel for the past 15 years. My experience mirrors yours: I had to force myself to use it for the first two weeks. The following 178 weeks you would have had to pry it from my cold, dead, fingers. It is however a thumb-ball, not a palm-ball like like Kensington, and the trick to efficient usage is to set the sensitity to maximum. Really, try it. Logitech never understood the greatness of the device and they have slowly phased them out. They only sell the wireless version now. I bought a couple of the wired model on sale once and I am now down to my last two. The switches wear out, unfortunately.
