It's fun to use older technology and experience the durability, and nice build quality in comparison to modern peripherals. However, ergonomics does factor into the choice of pointing devices.
The problem I have with mice in general is they're always too narrow. Gripping these narrow mice causes my thumb and pinkie to stay in a cramped position. Over long periods of time, this can cause cramps, pain, and RSI. I can relax my pinkie and use my ring finger to grip the right side of the mouse. The pinkie is then dragging on the mouse surface. I have the tendency to curl my pinkie to tuck it out of the way. Over time, that has caused pain in my pinkie joint.
Considering all this, the adjustability of the MadCatz mouse is very appealing to me. I'm hoping it has sufficient width adjustments to alleviate the hand cramping and pinkie stress of narrower mice. Of course, the MadCatz mouse should at least triple my frag ratio and increase my geek cred and improve life in general. :biggrin:
