I'm the same.
My PC plugs into a monitor and my living room TV, so I buy for that mostly as it results in the best performance.
I have PS5 for exclusives and my son.
I have a Switch for exclusives and portability. ( I even have a Vita for extra portability).
PersonallyI could live without a portable Switch 2 as I'm planning on going for a next gen Steam Deck or an equivalent once they can handle current gen games.
However I'm definitely not the main market for a switch and I reckon good enough graphics combined with portability has been its greatest selling point.
