> But if you do that then many users will in fact leave the mouse plugged in permanently, "just in case", effectively transforming it, in their experience, from a nice wireless mouse to a dodgy wired mouse.

I had a reasonably cheap wireless mouse back in the early 2000s which could take rechargable lithium batteries and charge them with a wire that also allowed me to use the mouse at the same time.

I'm no power user, that device lasted me years and the reason it's still not used all the time is the cable frayed and died after 10 years.
