Why are Nintendo Switch sales peaking much later than other Nintendo consoles?

[Leynos]

Wii also only had one thing going for it. A novelty. Novelties wear off. The switch has a practical use for its selling point. It's convenient having the ability to be both docked and handheld. As HDTVs became more common and Smartphones the less sense Wii made. Switch released just before the cloud gaming boom and it's more practical than cloud gaming IMO. I'm not saying this is the sole factor. Just an additional one to what has already been mentioned.
