HTML5 support still sucks. I work with companies daily who are forced to use old versions of IE. So, we're forced to use plain HTML to build our business on, technology is going backwards.
HTML5 support doesn't suck. Check out http://caniuse.com, and you'll notice that non-IE browsers are doing a rockin' job supporting HTML5. If you develop for iOS or Android, HTML5/CSS3 has been a joy. Sure, there are hiccups, but support is far from "sucking".
It sounds like your companies upgrade policies suck! OR, their decision to support/build around proprietary web technologies, hindering their ability TO upgrade. That sucks.
