Considering purchasing a Lenovo Legion Go S but prefer not to use Windows? Valve has a solution for you.

This week, Valve announced a significant upgrade to SteamOS — the Linux-based operating system that runs its well-known Steam Deck handheld gaming console. This update introduces an important new feature: the capability to install SteamOS on devices other than the Steam Deck. As per Valve’s official support documentation, the only non-Steam Deck device receiving full, official support at launch is the forthcoming Legion Go S, which is anticipated to debut later this month. Nevertheless, Valve states they are actively pursuing broader compatibility with additional devices in the future.

While it was technically feasible to get SteamOS running on other handheld PCs previously, the process was far from straightforward and often involved complex workarounds. Thanks to this new update, users of the Legion Go S can look forward to a significantly smoother and more hassle-free installation process.

Valve also mentioned in the update notes that SteamOS now provides “enhanced support” for other AMD-powered handheld devices, including the original Lenovo Legion Go and the Asus ROG Ally. Although these devices don’t currently possess official support, the enhancements indicate that users might still be able to install and operate SteamOS — albeit with a few challenges. Full official support for these devices may likely be introduced in a future update.

For those who are new to handheld gaming PCs, this is a notable advancement. Most devices in this segment are shipped with Windows, which, while flexible, isn’t always the most user-friendly or efficient experience for gaming on the move. In contrast, SteamOS is specifically designed for handheld gaming, presenting a cleaner, more intuitive interface. That being said, Windows still maintains an advantage when it comes to game compatibility, so the decision between the two platforms will ultimately rest on your preferences.

With SteamOS becoming available on additional devices, the impending release of the Nintendo Switch 2, and the recent launch of the Backbone Pro mobile controller, there has arguably never been a better moment to explore portable gaming.
