Just to be clear, the rest of the browser world offers modern browsers across a wide array of operating systems. Microsoft can't even be bothered to offer a modern browser across more than two of their own Operating Systems.
Chrome spans at least 7(And that's a conservative estimate) Operating Systems. Firefox the same. And both update in a sane manner.
It's nice that Microsoft offers a good solution to the 5% of users on the cutting edge, but they are still ludicrously behind the curve.
