Not a great comparison because people lose and break charging cables all the time, so there's a much better profit angle there.

I suppose it's possible to lose Switch Docks, and some must break, but it's such a rare thing to happen that it doesn't really justify the razor-and-blades model.

Usually the docks outlast the tablet itself (this has happened to me once, so I actually have a spare Switch 1 dock)

re "profit angle"... our Switch 1 stopped working last week, I assumed a charging port failure. No amount of trying to hard reset or leave on charge for days could nudge the little red battery off empty. I have to assume it's 5 years old at this point. So we sent it back to Nintendo to find out if it's salvageable at all. They told us today that it's the main board, and they'll replace it under warranty (what warranty?!) and we'll have it back Monday.

They don't seem to be one of those companies that's trying to squeeze maximal money out of their customers at every opportunity.
