Performance, interoperability, and standards. Surely, there can be some common ground to be had here? Apparently, as stated by the powers behind the browser offered for Windows users by default, it’s just too much to expect. It’s “complicated” to be cutting edge and keep things in sync with Web standards.
Yes, this is going to go over badly from what I have been able to see. Worse is that we are still on IE8 with IE9 likely being a bit down the road. Nevertheless, people are already showing significant concern over IE9 and whether or not it will mean yet more browser juggling for developers.
In the end, I suppose one could conclude that Microsoft is willing to give Web standards a shot, when it meets with its vision of the future. It’s unfortunate, but this does seem to be the approach that the company is choosing to take in this instance.
