Steam Deck is a Linux desktop trojan horse Switching from Windows to Linux is pretty easy nowadays -- unless you're a gamer. If you are into PC gaming, Windows is still the best operating system for maximum compatibility and performance. Gaming on Linux has gotten better thanks to Steam's Proton, but still, Windows clearly reigns supreme. With all of that said, Linux gaming is about to get much more possible. You see, Valve's new handheld gaming console is basically just a PC running an Arch Linux-based operating system. The OS is named "SteamOS" and it uses KDE Plasma. What is this new device called? Valve calls it "Steam Deck," and it starts at just $399. At this price, it not much more expensive than the much less powerful (and less capable) Nintendo Switch. Steam Deck is finally bringing Linux gaming to the mainstream.
