The Steam Deck is a portable, handheld PC that will ship with Valve's own SteamOS (built on top of Linux). The device is billed as an entirely open platform, letting players install games outside of the Steam ecosystem, run additional PC software alongside them, or just replace the entire OS with Windows if they like. Valve is hoping that most (not all) games will work just fine on SteamOS when the Steam Deck launches, with a lot of work going into improving Proton--a compatibility layer that allows Windows games to run on Linux without native support, and without (too many) issues.
