Similar thing happened to me. I borrowed steamdeck, realized that i don't like handhelds but i liked gaming on Linux. So i bought a laptop that replaced my macbook for work but it games better than steamdeck.

I use my Steam Deck as a game console, connected to my beamer and with 4x PS5 controllers. Works great for that with the Steam game mode. But yes it's been a long time since I played anything on the big screen.
