Steam users are not a "fair representation of all users" either. The gamer demographic is biased towards newer and faster hardware than the average user, and the newest greatest hardware is only going to be supported on the latest OS version(s).

I agree. I claim that both sets are biased, whch is why we can't use the steam charts or Firefox usage data to draw any conclusions about the broader population
