I wish media outlets would stop pretending that mobile devices running Windows are rivals to the steam deck, though. A very large portion of the deck's magic comes from SteamOS, which has loads of things built into it to benefit mobile gaming. Streamlined game updates, low overhead OS, quick booting, quick suspend/sleep, custom control hardware, and more.
All these devices running Windows are just laptops in a less versatile form factor. That's all well and good, but I don't see how they really have much to do with the steam deck except for the fact that they're portable and have a built in controller of some sort.
Valve said they want to partner with companies to support it on other devices. Guess they haven't taken up Valve's offer for whatever reason. They should also have more faith on just how well proton works.
