Valve's SteamOS Debuts on Third-Party Gaming System

Lenovo's Legion Go S: The First Third-Party SteamOS Handheld

Lenovo has unveiled the Legion Go S, a groundbreaking handheld gaming PC that will be the first non-Valve device to ship with SteamOS. This marks a significant expansion for Valve's Linux-based operating system, previously exclusive to the Steam Deck.

The Legion Go S, launching in May 2025 for $499, offers a compelling alternative to Windows-based handhelds. Unlike Windows, which can be less optimized for portable devices, SteamOS provides a smoother, console-like experience. This has been a key advantage for the Steam Deck, and now extends to the Legion Go S.

While the Legion Go S will be available in a SteamOS version (16GB RAM/512GB storage), Lenovo will also offer a Windows 11 version (launching January 2025) with options for 16GB RAM/1TB storage ($599) and 32GB RAM/1TB storage ($729). The SteamOS version boasts full feature parity with the Steam Deck, ensuring consistent updates.

The success of the SteamOS Legion Go S could influence future SteamOS adoption. Although the flagship Legion Go 2 currently lacks SteamOS support, strong demand for the S model may change that. Furthermore, Valve's announcement of a public SteamOS beta for other handhelds in the coming months opens the door for wider compatibility beyond Lenovo. Currently, Lenovo holds the exclusive license for a SteamOS-powered handheld from Valve.
