"Who is still using IE ??"
Well, if you're using IE9, why not? I'm just gonna come out and say it - there is nothing wrong with IE9. It's not as bleeding-edge advanced as other browsers, sure, but there's also not really anything inherently wrong with what it does. It's quick, seems stable when I've used it, supports the current standards far far better than older versions - what exactly is wrong with it, other than it not being fashionable these days? (Seriously, if you follow *trends* for a feckin' web browser, you need to re-assess your entire life.)
Wanna know how many rendering bugs I've had to fix in IE9 recently, or indeed ever? None. Zero. Zilch. Nada. Doughnut.
Wanna know how many I've had to work around in Chrome in the past fortnight? Because it's not zero.
Personally, I'm a shirt-wearing Mozilla man, but I'm no zealot.
