The upcoming release of the Steam Deck could mean great things for gaming on Linux. The handheld PC due to ship in December 2021 (provided you're one of the lucky few pre-order customers who managed to catch the initial stock) is Valve's latest attempt to break through in the hardware market, following the earlier Steam Machines project with renewed focus and dedication.

While the Steam Deck will allow you to install Windows on it, by default it runs a modified Arch Linux distro with the latest version of SteamOS. Games will run through Proton, a compatibility layer that Valve is working hard to improve so that it may be compatible with an even greater spectrum of titles.
