I've definitely browsed the web on my Steam Deck when I wanted to install a fan patch to a game, but I imagine I am in a small minority. Pretty sure the Steam Deck doesn't even ship with a browser, since I remember manually installing Firefox. And booting into the desktop mode has its own friction, and it's not exactly a smooth experience to use a Linux DE on the touchpads / touchscreen. These days I actually just opt to download everything on my actual desktop computer and just SSH them to the Steam Deck.
