Valve's SteamOS Debuts on Non-Valve Hardware

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, marking a significant expansion for the popular Linux-based operating system. This exciting development opens up the smooth, console-like SteamOS experience to a wider range of gamers.

Initially exclusive to the Steam Deck, SteamOS offers a distinct advantage over Windows-based competitors like the Asus ROG Ally X and MSI Claw 8 AI+. Its optimized performance for portable devices provides a significantly smoother user experience. Valve's efforts to bring SteamOS to third-party hardware have culminated in this partnership with Lenovo.

The news, initially hinted at through leaks, was officially confirmed at CES 2025. Lenovo unveiled two new Legion Go handhelds: the Legion Go 2, a successor to the original Legion Go, and the Legion Go S, a more compact and lightweight alternative. The key differentiator? The Legion Go S will be offered in two versions: one running Windows 11, and the other, the groundbreaking SteamOS edition.

Lenovo Legion Go S Specifications:

SteamOS Version:

• Operating System: Valve's SteamOS
• Launch Date: May 2025
• Price: $499 (16GB RAM / 512GB storage)
• Feature Parity: Full feature parity with the Steam Deck, including software updates (excluding hardware-specific adjustments).

Windows 11 Version:

• Operating System: Windows 11
• Launch Date: January 2025
• Price: $599 (16GB RAM / 1TB storage), $729 (32GB RAM / 1TB storage)

The $499 SteamOS version of the Lenovo Legion Go S will be available in May 2025, offering a compelling alternative for gamers seeking a streamlined, optimized handheld experience. For those preferring Windows, the Windows 11 version will launch earlier in January 2025, at a higher price point. While the flagship Legion Go 2 currently lacks a SteamOS option, this could change depending on the success of the Legion Go S SteamOS version.

Lenovo's collaboration with Valve is currently unique, but Valve has announced a public SteamOS beta for other handheld devices in the coming months, hinting at broader availability in the future. This expansion significantly broadens access to the SteamOS experience beyond the Steam Deck.
