Steam Deck gives you easy, mobile access to your Steam library. It’s an all-in-one mobile gaming solution that can also function as a full desktop PC in an instant by plugging in a keyboard and mouse.
5 Reasons Why YOU Should Buy a Steam Deck
If you already own a gaming laptop, you might not need a Steam Deck, but the device offers more than just mobile gaming.
The Steam Deck is a handheld gaming computer made by Valve, the company behind the Steam platform. It features the same hardware that you would find in any other gaming PC, only in a much smaller package with a built-in screen and game controller.
It looks like a handheld like the Nintendo Switch, but it plays PC games and offers easy access to your Steam library. It runs SteamOS, Valve’s Linux-based operating system. Power users can also access a full Linux desktop mode.
