SteamOS, Valve’s acclaimed Linux-based operating system, now officially supports a second handheld device, opening the door to a new era of portable gaming innovation.
If you’ve followed the evolution of handheld gaming PCs, you know one name has dominated the conversation: Steam Deck. But the landscape just shifted. What does this mean for gamers, device makers, and even Microsoft?
Why SteamOS matters in the Handheld Arena
SteamOS isn’t just another operating system—it’s the secret sauce behind the Steam Deck’s runaway success.
Its streamlined, console-like interface strips away the headaches of Windows on a small screen, letting players jump straight into their libraries with minimal friction.
Now, with Valve’s commitment to expanding SteamOS compatibility, the benefits are reaching beyond their own hardware.
What sets SteamOS apart?
- Optimized Performance: SteamOS is tailored for gaming, prioritizing frame rates and battery life over background processes.
- Console-Like Experience: The UI is intuitive, making handhelds feel more like dedicated gaming consoles than shrunken-down PCs.
- Open Ecosystem: As a Linux-based platform, SteamOS is less encumbered by bloatware and licensing restrictions.
Lenovo Legion Go S: The first official SteamOS alternative
The Lenovo Legion Go S is the first non-Valve handheld to receive official SteamOS support, and it’s a game-changer for several reasons.
Priced competitively and boasting outstanding ergonomics, the Legion Go S is designed to go head-to-head with the Steam Deck.

Hands-On Insights: SteamOS on New Hardware
Having spent time with both the Steam Deck and a Legion Go S running SteamOS, the difference is immediately apparent.
The Legion Go S’s larger, brighter screen and more comfortable grip make marathon sessions less fatiguing. But what really stands out is how SteamOS elevates the experience compared to Windows:
- Faster Boot and Resume: SteamOS boots quickly and resumes games almost instantly, while Windows often bogs down with updates and background tasks.
- Better Game Performance: Early tests show that SteamOS can squeeze more frames out of the same hardware compared to Windows, thanks to lower system overhead.
- Battery Life: With fewer background processes and smarter power management, SteamOS extends playtime on the go.
One surprise: even with the Legion Go S’s higher screen resolution, SteamOS manages to deliver smooth gameplay—something Windows struggled with on the same device.

What this means for the future of Handheld Gaming
Valve’s move to open SteamOS to third-party handhelds is a seismic shift. Here’s why:
- More Choices, Less Compromise: Gamers can pick the hardware that fits their hands and budget without sacrificing the seamless Steam experience.
- Pressure on Windows: Microsoft now faces real competition in the handheld space, especially as SteamOS outperforms Windows in key areas.
- Community Innovation: With SteamOS’s open-source roots, expect modders and manufacturers to push handheld gaming in exciting new directions.
Final words
SteamOS officially supporting a second handheld isn’t just a technical milestone—it’s a signal that the era of flexible, console-like PC gaming on the go is here.
Whether you’re a Steam Deck loyalist or eyeing the Legion Go S, one thing is clear: the future of handheld gaming is brighter, faster, and more open than ever.
