A Steam Deck is a handheld gaming computer developed by Valve and released on February 25, 2022. It is a portable PC gaming device that allows users to play Steam-based games while on the move. The device uses Valves Linux distribution SteamOS, which incorporates the namesake Steam storefront. SteamOS uses Valves Proton compatibility layer, allowing users to run Windows applications and games. The Steam Deck was built for extended play sessions, with full-size controls positioned perfectly within reach. In addition to handheld use, the Steam Deck can be connected to a TV or monitor through a docking station and be used like a desktop computer or home video game console. The Steam Deck comes in three storage options: 64GB, 256GB, and 512GB, with no in-game difference in frame rates or graphics quality between the three models. The Steam Deck supports local area network (LAN) file transfers, a feature that lets you transfer Steam games from one gaming PC to another on the same network.
