I hate to go off topic, but you make some pretty bold statements there about linux.
First of all, most of the software developed for linux is free and under opensource -- so it's kind of hard to 'steal most of their software.' Many of the apps you find in Windows have free equivelents (or better!) in linux :]
And about the commandline thing... ever heard of X? It's a graphically-enabled window system for linux, and works quite well :]
Linux is developed for running servers anyhow, so gamers normally wouldn't need to be interested in it
