I hope they can be held accountable for mistreating those 'transplants" (what an ugly word!) too. But I guess that would be easier here in EU than in USA.

When you pay them as long as you use the mouse, they have a business reason to keep it working as long as possible (so to use batter switches) and sending you a new one when one breaks can still be profitable for them. Software updates are less important here.

I guess for end users it will still be cheaper and more convenient to buy a new regular mouse with a one-time payment after the previous one breaks. And that is how electro-trash piles up…
