Update on Trackball

Just a quick update on the Slimblade trackball.
... After a little software adjustment and practice, I find it gives me the best combination of speed and precision I ever had. I can zip across two wide screens in half a second, and yet make as precise work as I've ever made.
Admittedly I was a bit in doubt there in the beginning, it felt tricky to control, but it was just sorta like getting a different bicycle.
