It might seem like minutiae, but, safari also doesn't pay any attention to SVG specs. This makes the pages I build for beaver [1] like, impossible. They work beautiful in chrome; but they don't work at all in safari; and because of that, I can't really explore what potential experiences pushing the limits on SVG might have for my clients. Whatever you build has to work in all clients. It's a sad state of affairs, because if safari wasn't so far dilapidated, I would have been able to build some really impressive experiences; but, without safari support it's a no-go.
