Any reason to not support h264, which seems to have similar levels of browser support? (trades Firefox on Linux/OS X/WinVista for support on IE/Safari/iOS/Android)
That trade might not be equal. As it is, the second one there according to the article only makes up 14% of traffic. I've got to imagine that Firefox makes up a significant portion of the 86% left. Couldn't guess about the platforms though.
