Lenovo Legion Go S: The First Third-Party SteamOS Handheld
Lenovo's upcoming Legion Go S gaming handheld will be the first non-Valve device to launch with Valve's SteamOS pre-installed. This marks a significant expansion for SteamOS, previously exclusive to the Steam Deck.
The $499 Lenovo Legion Go S, launching in May 2025, offers a compelling alternative to Windows-based handhelds. While competitors like the Asus ROG Ally X and MSI Claw 8 AI+ boast impressive specs, the Legion Go S leverages SteamOS's optimized Linux-based architecture for a smoother, more console-like experience. This has been a key advantage for the Steam Deck, and now extends to a broader market.
Rumors of a SteamOS-powered Legion Go variant proved accurate at CES 2025. Lenovo unveiled both the Legion Go 2 and the Legion Go S. The Go S, a more compact and lightweight version, will be available in two configurations: one with SteamOS and another running Windows 11.
Lenovo Legion Go S Specifications:
SteamOS Version:
- Operating System: Valve's SteamOS (Linux-based)
- Launch Date: May 2025
- Price: $499
- Specifications: 16GB RAM / 512GB storage
Windows 11 Version:
- Operating System: Windows 11
- Launch Date: January 2025
- Price: $599 (16GB RAM / 1TB storage), $729 (32GB RAM / 1TB storage)
The SteamOS Legion Go S will offer full feature parity with the Steam Deck, receiving identical software updates (excluding hardware-specific adjustments). The Windows version provides an option for users preferring a familiar operating system. While the flagship Legion Go 2 currently lacks a SteamOS option, future availability depends on the success of the Go S.
Lenovo is currently the sole manufacturer partnering with Valve for a licensed SteamOS device. However, Valve announced a public SteamOS beta for other handhelds in the coming months, opening the door for broader compatibility.
