I upgraded from the Microsoft Touch Arch mouse to the new TouchMouse. I must say I am not a fan.
The new mouse looks nice and all but does not work as well as I would like.
The new TouchMouse has a single button. It utilizes touch sensors to detect if you are using the left or right finger to press down. The problem that I have it is I rest my fingers on my mouse. This causes the mouse to think I am using the multi-touch (two finger) to minimize or maximize windows. It also sometimes thinks I am pressing the right button when I press the left.
