I love Valve but it seems like they create these hardware projects to occasionally remind platform owners like microsoft/playstation/nintendo that they can't completely abuse their users and software devs (Win10 store lock-in, etc) and retain all of them.

And yet it looks like you cannot use the Steam Deck without logging into a Steam account. Looks like we are trading in one lock-in for another.
On the hardware page they show it docked and running a normal desktop interface and say "Use your Deck as a PC. Because it is one" and "You can also install and use PC software, of course. Browse the web, watch streaming video, do your normal productivity stuff, install some other game stores, whatever."
On the spec page, it says the OS is SteamOS 3.0 (Arch-based) and Desktop is KDE Plasma.
I guess I'm just not understanding where you'd even get the impression that it would be locked into a Steam account.
