people are trained and tested to type fast on the 10-key, so it should stay on the right side. navigation keys should move to the left side.

Logitech MX Revolution is my ideal mouse. Been using it for 10 years ever since it first came out. $100 when it came out and totally worth every dollar.

Pros:

It has perfectly ergonomic shape.
Plenty of buttons that I can customize.
I put common keys like space, backspace, enter, copy, paste ...
