The anti-IE in this presentation is strong. Or rather, the anti pre-IE9. I have multiple clients that simply NEED me to support IE and be reasonably close in interaction to their modern browser counterparts. Banks are one of them. CSS3 animation with fallback is the key.

Animations are not a core part of functionality.

If your users are using IE, surely they only expect it to 'work'.
