The same way that counting Android phones as desktop does?

Nothing alike. Steam Deck is running a full Linux distro under the hood, using existing repositories for updates, along with their own launcher (not DE).

On the contrary, XBox has the full disposal of Windows Store and UWP applications available to it.

So no difference than using Windows 10S, 10X or whatever other UWP only variants Microsoft has released thus far.

UWP is nothing like it. Steam Deck is just running Linux with an existing DE, with some Valve-supported software and drivers.

Indeed, XBox runs two versions of Windows via a type 1 hypervisor, one version is a minimal Windows kernel tailored for gaming, while the other supports the OS services required to have the UWP runtime running on the same hardware.

Not at all the same thing. /s

Indeed, Steam Deck runs one version of Linux (based on Arch) and enables Windows games through a non-virtualized compatibility layer (Proton, forked from Wine).

Not at all the same thing.

Whatever dude, we will see the hard numbers quite soon.

Steam Deck isn't a desktop tho

It is if you plug a monitor and peripherals. Runs a full KDE Plasma desktop.

Ah, then we can add Xbox to the amount of Windows desktops in use as well.

The Xbox doesn't show a Windows desktop when you plug stuff in. Your constant trolling on Linux threads isn't appreciated.

It is called experience from a failed Linux Desktop sales pitch.

Been there done that.

Ex-Linux zealot, whose digital trail even includes emails using M$ on the signature.

You've gone from being one zealot to another. Oh well, whatever floats your boat.
