It's bizarre to me that we've gotten so used to disposable things these days that we're conditioned to think of replaceable batteries as an odd feature.
I remember when Powerbooks had batteries that were not just user-replaceable, but field-replaceable.
In headphones? I think it’s a bit dump. The form factor is more important. I would be happy for replaceable battery in MacBooks tho.
It used to be replaceable in the macbook without any tools. Then that was whittled down to requiring a phillips head, and eventually taken away entirely.
The PowerBook G3 with dual hot-swappable battery/drive bays was peak fucking laptop design.
