The title could mention Steam Deck, but not mentioning it makes better clickbait. Warning: This reply has some random thoughts about the system being or not being a game console.
I personally don't like calling the Steam Deck a game console, but I get why it is seen as such. The reality is, it's a PC in handheld form factor treated as a game console. I guess the one important distinction is, that developers can target the Steam Deck specifically, which makes it a game console like PC. The other handhelds or laptops based on PC technology aren't consoles, even though the concept of the Deck existed before. That's why I do not consider any specific PC configuration, such as Aya Neo or the other competitors a game console. Because developers do not target those specifically (and they lack an operating system dedicated being a console).
The reality is, the lines between game console and general computing devices get blurry, once you involve "real" PC hardware and operating systems suited for general operations. And the Steam Deck has both. It's tricky. But I really like the fact that the Steam Deck can be targeted and optimized by developers and that Valve takes their time for an iteration of the "system". What we were thinking of game consoles changes with this open platform. And the best thing is, the game library does not depend on this specific hardware; you are not bound to a specific company in example, not even a specific shop or library.
Valve entering the game console market with a Linux based system is probably one of the most important steps in videogame history. I suspect this will have bigger impact in the future than most people imagine now. At least I hope so...
