According to The Verge, Valve confirmed its intention to extend support for its Linux-based SteamOS to rival gaming handhelds, including the ASUS ROG Ally. This move marks a significant step towards realizing Valve's decade-old vision of a widespread "Steam Machine" ecosystem. Lawrence Yang, a designer at Valve, confirmed to The Verge that the company is actively working on adding support for additional handhelds to SteamOS. This revelation came after eagle-eyed observers spotted a curious line in Valve's latest SteamOS 3.6.9 Beta release notes mentioning the addition of "support for extra ROG Ally keys." While the development is still in progress, Yang emphasized that SteamOS isn't quite ready for out-of-the-box use on rival devices. However, he assured that the team is making "steady progress" towards this goal.

This initiative doesn't necessarily mean that manufacturers like ASUS will officially endorse Valve's installer or ship their devices with SteamOS preinstalled. Many companies, including ASUS, have cited various reasons for sticking with Windows, including Microsoft's dedicated validation teams that ensure compatibility across diverse hardware configurations. Other devices, such as Lenovo Legion Go, AYANEO, and GPD Pocket 4, ship with Windows, but it could be interesting to see with SteamOS. Alongside support for third-party handhelds, Valve is also working on a general release of SteamOS 3 for non-handheld PCs. Finally, Valve hasn't forgotten about its promise to enable dual-booting on Steam Deck devices. While there's no specific timeline, Mr. Yang confirmed that it remains a priority for the company. We remain to see how this will materialize, and with added bells and whistles to SteamOS, the adoption of Linux-based gaming could be pushed even further.
