I like the concept for graphics-heavy pages, but for any text-oriented page ... well, any website that didn't support highlighting (which I use to keep track of where I am on a page) and that didn't re-render when zooming (absolutely necessary for high-res displays, where a page might show up tiny and need to be re-scaled) would be a website that I didn't stay at for very long.
