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 consumers a new choice in handheld PC gaming.
The Legion Go S, launching in May 2025 for $499, will feature Valve's Linux-based SteamOS, providing a smooth, console-like experience optimized for portability, unlike Windows-based competitors. This addresses a key advantage the Steam Deck held over rivals like the Asus ROG Ally X and MSI Claw 8 AI+.
Revealed at CES 2025 alongside the higher-spec Legion Go 2, the Legion Go S boasts a lighter, more compact design while maintaining comparable power to the original Legion Go. However, the availability of a SteamOS version significantly broadens the appeal.
Lenovo Legion Go S Specifications:
SteamOS Version:
Windows Version:
Valve has confirmed full feature parity between the Legion Go S and the Steam Deck, ensuring identical software updates (excluding hardware-specific adjustments). A Windows 11 version of the Legion Go S will also be available, offering a more familiar OS for those who prefer it. While the flagship Legion Go 2 currently lacks a SteamOS option, future plans may change depending on the Legion Go S's market reception.
Currently, Lenovo holds the exclusive license for a SteamOS-powered handheld. But Valve's announcement of a public SteamOS beta for other handhelds in the coming months suggests broader compatibility is on the horizon, opening up exciting possibilities for owners of devices like the Asus ROG Ally.
