I actually hope that Microsoft doesn't do that. Because I like that stuff like the SteamDeck improves the Linux-based Ecosystem.

If everyone now builds and buys Windows Handheld devices, it probably goes the same route as mobile phones, where a standard Linux or custom ROMs are second class citizen (if you are even allowed and able to use those) and you have to disable or downgrade security mechanisms if you want to install your own operating system.

I would really like if those hardware vendors would come together and improve the Linux gaming experience for their devices.
