I can simply put my opinion as Gaming and Performace is more important than programability and security. XP home run's perfectly on my computer, I run a firewall and anti-virus just incase, and i have yet to be hacked. I don't care as much about tweaking my OS as much as i do tweaking my BIOS to squeeze the most FPS out of my comp. Yeah, Linux would make a good OS for a server, but Windows makes a good OS for gaming.
