Seriously, you guys...
If any of you get satisfied by an operating system, you need new values in your life.

And if you don't understand that not everybody wants to prioritize spending a large percentage of their free time on learning an additional operating system (or a first one, for that matter) then you need a life for those values.

Learning how to get the best out of an operating system is not knowledge, it is time that should have been used on something else. We're geeks in here. But don't expect everyone else to be.
