If you only look at the numbers, you would assume that Microsoft has absolutely nothing to worry about. However, numbers rarely tell the entire story.
Over the past few years, Valve has quietly managed to make Linux gaming feel legitimate. It’s not perfect or remotely mainstream (yet), and it’s not going to be dethroning Windows overnight. However, Linux still feels legitimate enough now that millions of gamers are now seriously considering a future where Windows may no longer be mandatory or synonymous with PC gaming. Valve has managed to do this not by attacking Windows head-on, but by simply doing better in the areas where Windows is weakest, and that’s why Microsoft should be running scared of SteamOS and what it could mean for PC gaming.
