They don't even necessarily have to beat the PS5/Xbox. I already own the former but sometimes lament not being able to play the many, many PC exclusives out there (or at least nothing released in the past 10+ years since my daily driver laptop has poor specs). Just recently I was wondering whether one of those all-in-one Lenovo desktop boxes would have decent enough specs to play current-gen PC games at halfway decent settings, and my guess is that they don't, but I don't want to go through the hassle of building a PC and definitely don't want a tower with a huge footprint.

Turns out the Steam Machine is exactly what I'm looking for.

I bought a steam deck to play Age of Wonders 4. Briefly got sucked into playing a Skyrim again.

Exactly. I have both PS5 and Xbox One X, but I still connect my Steam Deck to TV to play Hades II because the game hasn't come out on those two consoles yet.
