If you click the most expensive model and then click max/fast mode, the same task can easily cost 10 or 20x of the cheaper models

A used n3ds xl costs close to a switch 2 these days lol

I don’t know if you’ve noticed, but you can’t replace batteries on most modern portable computing devices these days.

I think it’s more to differentiate from Bluetooth (which amusingly also uses 2.4ghz)
