I had an old Ledger die recently and replaced it with a new one. Didn't even consider being potentially able to replace the battery, but it would have been nice.

On the plus side, I did get to do a "fire drill" of my recovery process, which did work, so that was nice.

I'm a large believer of long-living tools and things in general, so I prefer my tools to be repairable and maintainable.

Of course I can't achieve what I want all the time, but being able to use a fixed-function tool till some electronic component dies inside is way more attractive for me to send the same device to recycling or trash just because a part with limited life (and shorter time w.r.t. rest of the device in general) reaches ends of its life.
