> Make sure [the mouse is] wireless.

I disagree there — wireless mice & keyboards are terribly insecure.

Other than that, seems like some good advice here.

Ergonomics and security are different concerns; the best mechanism for addressing one, considered on its own, may be suboptimal from the perspective of the other.

True enough, but security is a sine qua non: a system must be sufficiently secure before one even begins to consider ergonomics or anything else.

I've found wired mice to be lighter. wireless can be heavy , depending on what kind of battery is used.

When I last used wireless mice they had two AA batteries and I found it a great relief to go back to a much lighter wired mouse. It hadn't occurred to me that newer battery tech might be lighter. Maybe I should take another look at wireless mice.

EDIT: The Logitech MX Master (a wireless mouse) weighs 145g including battery, and the M500 (corded) weighs 144g. That probably includes the cord, so the in-hand weight might be a little lower, but they're certainly close. Neato.
