Its so native to win vista/7 that it does not support windows xp which Opera/Firefox/Chrome ALL support WITH their performance improvements AND they've done so while staying ahead of IE9.

I guess if that's native, yes IE9 wins. I think in user's minds: if its built for MY operating system specifically its better than the other. However thats not true as even the tech unsavvy are flocking away from IE.

HOWEVER. I am glad to hear this news. It only means one thing. PROGRESS.
