The
Logitech MouseMan is one of the best
mice ever made. When
introduced it was one of the earliest
ergonomic mice. It has 3
buttons and
triangular in shape. It narrows toward the
wrist and looks a bit like a
footprint. Unfortunately it is a very
right handed mouse. I have not seen a
left handed version. There
is a
notch for the thumb on the side and the top of the mouse curves downward toward the
right.
The design is not as exagerated as the later mouseman models that came
out. It is very comfortable.
Unfortunately Logitech discontinued this model after a
while. But fortunately it's back! The design was reintroduced
again as a "gaming mouse" under the name of Wingman. It's gray
this time but has the exact same design. The original was both serial port and PS/2 ready. The reintroduced version does both PS/2 and USB.
Wingman is sold at about $40.
I went out and bought 2 more just in case. I'm using one of them at work instead of the standard issue Microsoft mouse. The MS mouse bulges in the wrong place and hurts my wrist after a while. My original MouseMan has lasted me over 4.5 years and the middle button is just now starting to fail.
