Valve will officially let you install SteamOS on other handhelds as of April

Valve is set to allow the installation of SteamOS on third-party handheld devices starting in April 2025. This move follows the announcement that Lenovo will release the first authorized third-party SteamOS handheld, the Legion Go S, in May. Pierre-Loup Griffais, a lead designer for SteamOS, indicated that a beta version for other handhelds will be available after March, although specific devices compatible with the OS have not been confirmed. However, there is existing support for devices like the Asus ROG Ally and Lenovo Legion Go. Valve emphasizes the importance of maintaining a unified platform for SteamOS, which will ensure consistent software updates and performance across devices. While users can download and install SteamOS on their own devices, manufacturers must partner with Valve to officially ship the OS. Currently, Valve has no partnerships beyond Lenovo for this initiative. The company is also open to discussions about potential collaborations for other form factors, such as living room boxes. Valve has not confirmed any rumors regarding new hardware, including a Steam Controller 2 or VR headset, but hinted at future Steam Input compatible controllers.
