Lol, amusing post.. But in all seriousness the iFrame is incredibly useful when developing Comet-based webapps
I had never used iframes until I switched jobs and was tasked with upgrading a legacy application with literally hundreds of lines of javascript on many of the html pages- frequently set to run on onload(). Because a full rewrite was not an option- iframe came to be my salvation. Ajax just wouldn't have cut in this scenario.
The very feature/bug that this post culminates with is actually the very reason why iframes on iOS have become an invaluable and seemingly irreplaceable tool in my architecture. It is the lack of cross-site uncooperative content resizing that has kept a lot of my stuff confined to iOS.
Sounds like he has more of an issue with how iframes are implemented on various platforms than with iframes themselves.
Up until recently I had a similar issue with position fixed on mobile devices.
