I would rather think of different ways to interact with the web. To me, a browser is a "print" medium, like a newspaper. I would like to see television-like programming be distributed on the internet (or a separate version of the internet), that would allow me to watch the shows I want to watch, when I want to watch them. I certainly would want a "browser" that was tailor-made for this functionality, not some feature that was shoehorned into IE or Mozilla.
