I would consider paying the $5/month for Office 365 if Google ever took away my free domain email hosting.
Wow. Just... wow.
Nowadays there are frameworks like HTML5 boilerplate that help us along, but not so long ago it was extremely painful.
Worse are MS email clients even the most recent one which uses the MS Word engine to render html emails.
Further, if you want to create an innovative web app for mobile and desktop there is a ton more effort and work that needs to go in it if you want to reach the IE audience. It may not even work at all even after trying to get it to work - uggh!
Apparently this is actually a browser hang and not actually a crash. The friend reported it internally, but he said they probably wouldn't actually fix it in IE9 since it wasn't a crash and wasn't exploitable.
So, yes, the IE team is fully aware of this bug.
