It may have been one of the worst kept secrets in gaming hardware, but Lenovo's new Legion Go S is still real exciting. That's not only because this plucky handheld gaming PC packs one of AMD's new Z2 Series processors but also because it's available with SteamOS installed.
The Legion Go S and Legion Go S — Powered by SteamOS (that's the name) are two versions of the same 8-inch handheld gaming PC.
Both have been announced over at Lenovo's event at CES 2025. They're both available with one of AMD's Z2 Series Go processors, which were announced yesterday.
There's also a Z1 Extreme option, and both have a slightly larger 55.5 Wh battery than the original Legion Go. SteamOS is Valve's own Linux-based operating system for handheld gaming PCs, which has so far only officially resided on the Steam Deck.
It has been port-able to other devices, but no one has officially taken on the OS for their own device. Until now, anyways. I got a chance to have a quick play with the Lenovo Legion Go S at the event, and yep, that's a handheld alright.
