We could change its name as specs evolve, but the idea of (and demand for) an information browser will remain so long as humans find it desirable to not personally decipher the code for each page or application.
Hop into the iTunes Store - you're suddenly in an 'information browser.' As a general consumer, whether you're looking at information on the web or some other platform, you will be using a browser of some sort. A web browser just happens to be for the web, and that isn't going anywhere any time soon. The curve to change mass consumer behavior is extremely high once you've deployed a billion versions of a software concept and people find it comfortable and effective to use.
