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.

The official launch of the "Powered by SteamOS" program has been a long time coming; Valve's Lawrence Yang said as far back as 2022 that the company is "excited to see people make their own SteamOS machines." More recently, Valve confirmed that it was working on official SteamOS support for the Asus ROG Ally.
