Valve is making a notable shift with its portable gaming strategy as Lenovo debuted a new edition of its Legion Go gaming handheld that runs Valve’s custom operating system.

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.

Valve’s handheld device, the Steam Deck, wasn’t the first portable gaming PC ever created, but it is by the far the most successful. And like Steam becoming the de facto way people play PC games in 2025,

Windows 11 is often cited as the worst thing about handheld gaming PCs - but it looks like Microsoft could soon fix this.

Microsoft plans to merge Windows and Xbox for handheld gaming in 2025 Valve's SteamOS aims to be integrated into all gaming handhelds Microsoft must succeed with its hybrid to compete with Valve's expansion efforts.

The Steam Deck has been the biggest PC gaming hardware story of the last few years. So it’s no surprise that the idea of running SteamOS (perhaps the most celebrated component of that machine) on other handhelds like the Legion Go S is also a big deal.
