I had forgotten about Solaar. yes, it'll be easier to use than ltunify.

All you need to do is replace EITHER the laptop mouse OR the desktop
mouse with the unifying receiver version controllable with Solaar over
the USB port (Solar won't reach out to any receiver elsewhere).  The
nano receiver and unifying receiver speak different dialects so can't
understand each other and therefore shouldn't interfere even though they
are on the same 2.4GHz band.  At least I've not have issues, YMMV.

Or is you wan a nice new mouse, go ahead and nab one one.

There is one caveat to the unifying receiver: make sure you get a newish
version with the patched firmware (mouse jacking exploit), or you can
flash it yourself.  The attacker has to be fairly close (not quite in
your lap...) but its better to be safe when in public areas.
