One of my favorite things to come out of CES 2025 was the spread of SteamOS to other PC gaming handhelds, namely a new version of Lenovo’s Legion Go. On the show floor, PCWorld’s Adam Patrick Murray got his handheld-loving hands all over both versions of the Legion Go S — one running SteamOS,

The Lenovo Legion Go S with Windows or SteamOS also joins a prototype for the Lenovo Go 2, now with controllers you can comfortably hold.

The SteamOS Legion Go S model is the most interesting of the two since it's the first non-Steam Deck handheld that utilizes Valve’s operating system. If you’ve read any of our handheld reviews, then you know Windows 11 has been a major sore spot for these systems since Microsoft’s OS doesn’t work well on these systems.

SteamOS is slowly becoming an alternative to Windows for handheld gaming devices. After launching the Steam Deck with SteamOS, its own operating system, Valve is now partnering with third-party manufacturers so that they can release gaming handhelds with SteamOS support.

The Windows version of the Legion Go S is up for preorder ahead of its imminent release, while the SteamOS version is expected to arrive in May.

Lenovo has announced the Legion Go S, which will become the first third-party SteamOS handheld PC when it launches this May.

Lenovo Legion Go S pre-orders just went live at Best Buy, and you can now reserve the Windows 11 version for $729. There's no sign of the SteamOS model yet, which just so happens to the the handheld I'm most hyped for so far. However, if you'd rather embrace the versatility of Microsoft's PC operating system, this is the version for you.

The Steam Deck is no longer the only SteamOS-based gaming handheld on the market. A more expensive Windows version of the Legion Go S will be available first.

The Steam Deck might be amazing, but it's showing its age. Lenovo's new Legion Go S is here to duke it out at the $500 portable gaming price point.

Following months of rumors, the new Lenovo Legion Go S has finally arrived, and I'm pretty hyped to see there's a SteamOS version. While I wouldn't go as far to call the laptop maker's new handheld a Steam Deck, it should help normalize PC operating systems that are actually build for portable play.

As a loyal Steam Deck player, I’d be heartbroken if the news came out that Valve never makes a second generation. But at the AMD and Lenovo event named “The Future of Gaming Handhelds,” I got a chance to talk to Valve’s SteamOS designer Pierre-Loup Griffais (on the left) about it and the answers
