Lenovo has finally announced a new line of Legion Go handheld PCs, with one that will come installed with SteamOS out of the box. The new model is called the Legion Go S, and it's the world's first handheld PC from a third-party manufacturer using Valve's operating system.

SteamOS is slowly becoming an alternative to Windows for handheld gaming devices. After launching the Steam Deck with SteamOS, its own operating system, Valve is now partnering with third-party manufacturers so that they can release gaming handhelds with SteamOS support.
