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.
Honestly, if they do the opposite of this generation and hand a TV only version which is cheaper than the combo, and do not offer a portable only, I would consider. I rarely use portable, but am fortunate enough it isn’t only about the money. That said, I do like that the Switch offers a portable mode because so many people use it, and see the value in that. I mean the switch having such a large user base definitely helps the game selection, along with Nintendo removeding any sort of portable must free up opportunities for them to make more Switch games
