Legion Go S powered by SteamOS review: A purpose-built OS makes all the difference

The Lenovo Legion Go S powered by SteamOS is not only the first third-party device to come with Valve's platform pre-installed, it's also cheaper and slightly more powerful than its Windows 11-based sibling.

Earlier this year, Lenovo released a more streamlined and potentially affordable take on its flagship gaming handheld in the Legion Go S. Unfortunately, the Windows 11 version came first, which wasn’t the one we were most excited about. For fans of SteamOS, the main reason aside from price to pick a Steam Deck over the Legion Go S (or vice versa) is that each system features different performance targets. Valve's handheld has a TDP that tops out at 15 watts, and at lower power levels, it features better energy efficiency than the Legion Go S. This makes it more suitable for people who regularly play older games or less demanding 2D fare.
