Lenovo ships SteamOS on the Legion Go 2

The Windows Legion Go 2 reached shops in October 2025 in the United States, September in Europe, from about US$1,100 on the slower Ryzen Z2 and about US$1,349 on the Z2 Extreme in VideoCardz's comparison table. Notebookcheck's review unit was the Extreme SKU at €1,499. CES did not change those Windows prices. CES added a SteamOS SKU at US$1,199 for June. Lenovo put a dedicated Steam button on that SKU for the overlay and the shortcuts. The rest of the object is the object you can already buy with Windows: Hall-effect sticks, a right-side touchpad, detachable controllers, a kickstand, an FPS mode that uses the right controller as a mouse. Tablet-only dimensions are 206 by 136.7 by 22.95 millimetres. Controllers alone are 210 grams. With the grips on, 920 grams, 295.6 millimetres wide. That is a computer you hold with both hands.

The photograph of the handheld in the dark is the living-room fact. Analog sticks with light around the rings, a D-pad on the left, face buttons on the right, a square pad under the right stick, battery at 81 percent, 11:05 p.m. on the bar. The screen in that frame is a Legion library — Watch Dogs: Legion last played two minutes ago, Doom Eternal, Control, Skyrim, tabs for Cloud Games, Game Store, Library, Settings, Android Games. That is the Windows Legion software, not SteamOS. The picture is the hardware in a pair of hands. SteamOS is the June SKU's software. Valve's OS is the reason the June machine does not need a dual-boot hobby. The Steam Deck OLED is still cheaper. This one is faster, bigger, and already on Valve's OS if you buy the June box.

The kickstand is the other photograph. A black Legion Go 2 standing on a white marble nightstand, Lenovo LEGION on the 22.4 cm OLED, a brass lamp, a navy pillow, a small black charging case. That is the desk mode Lenovo has been selling since the first Legion Go: prop it, detach the controllers, use the right grip as a mouse. SteamOS does not remove the hinge. The 144 hertz OLED is the same panel Windows customers already have. VRR is the same. 500 nits is the same. 74 Wh is the same. What June changed is the firmware at first boot. Lenovo's CES language was "Powered by SteamOS." WCCFtech printed the full dimension table. Windows Central printed the US$1,199 floor. VideoCardz put the SteamOS row next to the Windows row and next to the Legion Go S, the ROG Xbox Ally X, and the original Steam Deck OLED. The Deck OLED is still the cheap ticket. The Legion Go 2 is the 22.4 cm ticket with the Extreme chip.

Configs above the US$1,199 floor take the Extreme chip, 32 GB, and 2 TB. Lenovo did not publish a full CES matrix of every SteamOS SKU. GamingOnLinux noted that exact SteamOS configs were still thin in January. By June the machine was the June machine. This desk is not a stock tracker. The reported copy is Lenovo's: SteamOS on the Legion Go 2 in June, from US$1,199, Ryzen Z2 Extreme available, 22.4 cm 144 hertz OLED, 920 grams with the controllers on. Notebookcheck, reviewing the Windows Extreme, had already called the 144 hertz OLED and the detachable controllers the reason to pick this handheld over a smaller Deck. SteamOS on the cheaper Legion Go S had already shown, in that same outlet's test, more than 30 percent more gaming performance than Windows on the same chip. That 30 percent is Notebookcheck's Windows-versus-SteamOS number on the Go S, not a promise about the Go 2 Extreme. Treat it as a prior measurement on a related box. Official SteamOS on the Z2 Extreme is the new fact.

Two USB4 ports will drive a display. The kickstand will hold the 22.4 cm panel on a nightstand. The Hall-effect sticks will not wear a carbon track in a year. The 74 Wh pack is larger than the Steam Deck OLED's. The 920 grams is heavier than a Deck. You feel the width. That is the point of an 22.4 cm 16:10 in the hands. It will run a Steam library, a browser, and a local model if you install one. Lenovo did not put a Neural Engine marketing sticker on the CES slide. AMD's Z2 Extreme is the APU. 32 GB of LPDDR5X-8000 is the pool. SteamOS is the OS that boots. US$1,199 is the floor.

Lenovo's CES table also listed the ports in the order a handheld actually uses them. One 3.5 millimetre jack. Two USB Type-C ports, USB4, DisplayPort 1.4, Power Delivery 3.0. One microSD reader. No Ethernet. No HDMI. A 65 watt USB-C brick in the box, 74 Wh in the shell. Charge is a USB-C job, same as the Deck. VideoCardz put the Windows Legion Go 2 at US$1,099 for the Ryzen Z2 and US$1,349 for the Extreme. The SteamOS floor at US$1,199 sits between those two Windows stickers. That is a software SKU priced as a trim. WCCFtech's dimension line is the one to keep in a pocket: 29.6 by 13.7 by 4.2 cm with the controllers, 920 grams.

The Legion Go S already shipped SteamOS. The Legion Go 2 is the bigger panel and the Extreme chip on the same OS. June 2026 is when Lenovo said the 22.4 cm box would boot Valve's software from the factory. The next number is a measured frame-rate table on SteamOS Extreme when a lab publishes one. Until then the news is the object: 22.4 cm 144 hertz OLED, Ryzen Z2 Extreme, 32 GB, from US$1,199, 920 grams with the grips on, and a first-boot that is Valve's OS rather than Windows.

Hall-effect sticks, a right-side touchpad, detachable grips, a kickstand, two USB4 ports, 74 Wh, 920 grams: that object list is the same on the Windows SKU and the SteamOS SKU. October 2025 was Windows in shops. January was CES naming June. June was the first boot on Valve's OS. The 22.4 cm 144 hertz OLED did not change between those dates. The Extreme chip did not change. The floor that changed is the OS and the US$1,199 SteamOS sticker sitting between the two Windows prices VideoCardz printed.
