This was just submitted a few hours ago:<p><a href="http://cbateman.com/blog/whats-missing-in-internet-explorer-10" rel="nofollow">http://cbateman.com/blog/whats-missing-in-internet-explorer-...</a><p>That's probably not even the full list of what's missing in IE10, as html5test puts IE10 way below the others in HTML5 features:<p><a href="http://html5test.com/results/desktop.html" rel="nofollow">http://html5test.com/results/desktop.html</a><p>I wouldn't hold my breath for WebGL appearing even in IE11. Whatever Microsoft is saying, the "security" of WebGL is not the main reason why Microsoft is not the adopting it - not even close. Just like security is also not the main reason why Apple is not allowing other JS engines on iOS.<p>The security reason is used mainly as a "reasonable" excuse to cover for the <i>real</i> reason why they aren't implementing it (they obviously don't want OpenGL to gain anymore traction that it has already gained in mobile and Linux). If security would be an excuse to not implement something, we'd probably still be in the dark ages of the web. Consider Flash, it's one of the least secure pieces of software out there, and yet it's also what enabled video on the web for everyone. It's the reason Youtube exists today.<p>The lack of support for XP, which is still like 40% of the market, means Chrome is still by far the most secure browser on XP, which is something companies who aren't going to get new PC's and Windows licenses anytime soon should start considering.<p>No full screen API, no Web Audio API, and no WebRTC (and no Opus either) are also very regrettable omissions from IE10, and it will be another year or two before it will get them. Who knows how far ahead Chrome and Firefox will be by then.
