I think I read recently that one of the Ubuntu distros has just released a version/upgrade that allows you to access Netflix.
More people would use Linux, too. For the average user, Linux has everything a person would need... except compatibility with Netflix.
I suspect that people are looking for alternatives to XP since MS discontinued support. Linux would be a perfect replacement. Especially since it tends to be more compatible with older hardware; old hardware that is currently running XP.
