I’ve never felt any need to use it. It doesn’t do anything my daily driver doesn’t except be a handheld console, and I don’t go anyplace where portability is needed. I bought it because it was a cool new tech thing, but I’ve never found a use for it.
I’m not making any claims that the Steamdeck is bad or not useful for anything. I’m merely stating that I personally have found no use case for it in my own life. I’m happy that you and others have.
