"It's not a games console, it's really a portable PC. You can plug it into a monitor or a TV, install apps and software, use it to watch streaming video, and more—even install other game stores on it, according to Valve.
Just like your PC, the Steam Deck is intended to be an open platform. You can install Windows on a Steam Deck and even install other game storefronts like the Epic Store (you probably have a pile of free games in that library) or Xbox Game Pass. We just don't really know how well non-Steam games will work on the Steam Deck, but it's an exciting idea that you might be able to play games from your other libraries on the Steam Deck, too.
You can even wipe SteamOS off the Steam Deck completely and just use it to run Windows, according to IGN, who got some hands-on time with the device. Pierre-Loup Griffais told IGN the Steam Deck "can pretty much run anything you can run on a PC."
