I appreciate the quality of the offering, and indeed I'm excited because I am currently building a product that uses Google's synthesis!
But it's the lack of care displayed here that's really disappointing. It's like nobody involved with this demo went "Hey, maybe people aren't using Chrome and we should at least not totally fail when that happens". It's disappointing; as a mostly front-end dev at a small company, I put a lot of time into making sure that things work cross-platform, even if I don't always get it right. It's disappointing that Google's culture doesn't rate that highly enough.
