> It would be a flop for a traditional console, but the Steam Deck isn't a console, it's a PC

I don't think people use it as a PC, but more like as a portable media center, the Switch and the PSP do that as well (even the PSP had a web browser!)

So it's wrong to picture the Deck as the exception, even thought it can and is a supported use case

They sell it and market its gaming capabilities

You see games, not office apps, emails or social media apps, you don't have front facing camera so you can't use it for your meetings
