I'd like to know what wifi cards you have, I have 6 wifi cards and none of them work correctly in linux. 1 actually works but the wifi range is about 60% lower then it is in windows. 2 of them used to work, until a regression hit the drivers and they have not been update in a longtime. Also saying Linux has superior hardware support to windows is a joke. Out of the box without internet it might, but overall it does not. excluding third party support make no sense.
As for the great article showing linux graphics stack beating out windows, I enjoy seeing all the games tested are old OpenGL titles, No on cares to play those games anymore
and windows 7 has terrible support for openGL. Since DX is superior in every way, john carmack agrees.
