    HTML 5 video: iOS devices won't play video tags in the
    DOM, they instead open in a standardized player. Apple
    also stops them from auto-playing on iPhone.

This is what makes Vine so useless on iOS outside of the native app. It makes it preferable to use GIF sans audio generally, whenever it's an option.

I get where Apple is coming from, but this is definitely sorely needed for some use cases.

It's not "iOS devices". It's the default browser, Safari.

If you use, say, iCab, HTML5 video stays embedded in the page -- to a fault. Often you won't be able to full screen the video, you end up having to zoom the page.

True. I use Opera on desktop, so I should know to use the distinction. I just hate the browser alternatives on iOS so much I repressed them. :)
