Valve partners with Lenovo to expand SteamOS beyond Steam Deck, challenging Windows' gaming dominance with optimized handheld experience.

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.

It's official: Valve's SteamOS will be available on more platforms soon, and the first handheld PC gaming device to adopt the operating system will be the new Lenovo Legion Go S. At CES 2025, it was revealed that the slim Lenovo unit will run on the Linux-based OS--, the same one used on Valve's Steam Deck.
