Lenovo is trying an experiment. In May, it will officially become the very first company outside of Valve to ship a handheld gaming PC with the Steam Deck’s wonderfully pick-up-and-play SteamOS instead of Microsoft Windows.

Today at CES 2025, Lenovo announced two new additions to the Lenovo Legion Go lineup, major upgrades to the Lenovo Legion Tab, and even gave a glimpse at the Legion Go 2 prototype!

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.

The Legion Go S is a streamlined PC gaming handheld and the first with SteamOS since Steam Deck; the Go 2 is a full sequel. The Legion Pro 7i gaming laptop also gets a silicon boost.

Lenovo has just announced the first licensed Steam OS handheld, and a short time with the device reveals a familiar experience.

At CES 2025, Lenovo announced a brand new handheld PC, the Legion Go S, and it runs Valve’s premiere operating system. The Go S has SteamOS pre-installed, and features an 8-inch screen with variable refresh rate (VRR), Hall effect joysticks, adjustable trigger switches, and other alluring traits not found in any model of the Steam Deck.

Following the reveal of the Lenovo Legion Go 2 prototype, we’ve put together a guide to everything we know about the gaming handheld.

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

Lenovo is already announcing one new handheld (or two depending on how you’re counting) at CES 2025. However, that isn’t stopping the company from looking ahead to its next portable gaming device by teasing an early prototype of the Legion Go 2.

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.
