Lenovo Legion Go S: The First Third-Party SteamOS Handheld
Lenovo's upcoming Legion Go S gaming handheld marks a significant milestone: it's the first non-Valve device to ship with SteamOS. This collaboration expands SteamOS beyond the Steam Deck, offering gamers a new option.
The Legion Go S, launching in May 2025 for $499, will feature a 16GB RAM/512GB storage configuration. This contrasts with the Windows 11 version of the Legion Go S, available in January 2025 at higher price points ($599 for 16GB/1TB and $729 for 32GB/1TB).
SteamOS's advantage lies in its optimized Linux-based experience, offering smoother performance compared to Windows on comparable handhelds like the Asus ROG Ally X and MSI Claw 8 AI+. While these competitors boast powerful specs, SteamOS provides a more console-like, user-friendly interface. This was a key selling point of the Steam Deck, and now it's extending to other devices.
Lenovo's announcement at CES 2025 confirmed earlier leaks regarding a SteamOS variant. The Legion Go S is positioned as a more compact and lighter alternative to the standard Legion Go, while the Legion Go 2 is the direct successor. Currently, only the Legion Go S will offer the SteamOS option.

Valve assures full feature parity between the Steam Deck and the Legion Go S, including identical software updates (excluding hardware-specific adjustments). The success of the SteamOS Legion Go S may influence future SteamOS partnerships for Lenovo and other manufacturers.
Beyond Lenovo, Valve promises a public SteamOS beta for other handheld gaming PCs in the coming months, opening up the experience to a wider audience. For now, however, Lenovo holds the exclusive title of the first licensed SteamOS partner outside of Valve itself.
