I - way back when - bought a Switch 1 because it played a bunch of the games that I could easily involve my kids/family in, and can come the times I’ve used it on battery with one hand.

However, that was also before the Steam Deck became a thing and haven’t really given Nintendo my patronage since.

The Deck also has an internal-only battery but replacing that at least is fairly straightforward (I have not needed to do so but was in the area when upgrading the storage card).
