Honestly I don't care much for IE8 or IE9. Not because of it's speed or security. It's lack of rendering pages is a joke.
Both Gecko and Webkit render pages better then Internet Exploder. Not mention the bulk of it.
True I could add the Chrome Frame plugin to it. But why should I have to. However it appears that the IE that ships with Winblows 8 actually has some potential. At least until Chrome and Firefox get a decently idea of what the hell they should do.
I'm not just talking about the rendering engine on IE with Winblows 8. I'm talking about how it operates when used on a touch screen. Both Chrome and Firefox do work on a touch screen, but lack the gesture support that Win 8 users have come to know and love.
Theirs a reason why IE isn't Open Source and why it never will be. They don't want the tech savvy IE supports to find out that IE really does suck. After all Microsucks does in fact learn from Apple who releases the source code to Safari to show everyone that it to sucks.
