At CES 2025, Lenovo announced a brand new handheld PC, the Legion Go S, and it runs Valve’s premiere operating system. The Go S has SteamOS pre-installed, and features an 8-inch screen with variable refresh rate (VRR), Hall effect joysticks, adjustable trigger switches, and other alluring traits not found in any model of the Steam Deck.

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.
