I have also feel that the web has become bloated and overloaded. I don't see what this has to do with the iPad. What I would like to see is a revival of the web with structural markup, fluid layouts and a minimum of distractions.

Is there anything about what you need to do which can only be done on an iPad? Such a revival is easier on a new platform where you don't know what to expect yet. However, I don't see anything which would prevent someone bold enough from cleaning up their part of the web.
