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 is trying an experiment. In May, it will officially become the very first company outside of Valve to ship a handheld gaming PC with the Steam Deck’s wonderfully pick-up-and-play SteamOS instead of Microsoft Windows. And at $499, it’ll be a true Steam Deck rival, joining it as one of the lower-priced PC handhelds you can buy.

The Lenovo Legion Go S with Windows or SteamOS also joins a prototype for the Lenovo Go 2, now with controllers you can comfortably hold.
