I love playing handhelds, even if I only play them in the house, but the handheld nature of the Switch feels pointless for me, when I can just play it on a TV in docked mode and nearly always get a better performing experience, and for 2D games that take advantage of the Switch screen in handheld mode I'm stuck with that sorry excuse for a d-pad and Joycon drift, plus absolutely awful wi-fi for online games.
That being said, I'd rather a new model/successor to close the gap between the two form factors, than go to like 4k 120fps docked 720p 60fps handheld.
