Oh, one other handy thing Roger with a trackpad, it's easy to just swap which hand uses it. If you do start having further problems with the right hand, just start using the left hand instead.

I'm seeing the Logitech model out there using the unified receiver:

Beyond that and the Apple one, I'm only seeing older laptop sized ones for the desktop.
