@lion For me and my partner, we keep our Steam Deck docked to our TV and in desktop mode with just a small bluetooth keyboard and mouse on the coffee table and it honestly works great for us.
Before we were using an old thinkpad that was showing its age.
Either way I really like it better than using chromecast or whatever or smart TV apps that are so much more limited. Like it's fun for us to put on music via youtube and then just open another browser tab and have that TAS videos twitch channel open and muted and seeing what fun combinations we get which is just impossible without using a computer
