Will phones like iPhone, G1 and Blackberry that have apps lead to the end of traditional browsers?

More and more phones are gaining the ability to do what used to only be possible on a pc in a web browser. The emergence of apps has made opening a browser, typing in the url and looking for the link as simple as clicking a button (or screen). I find that I can get what I need done on the internet just as easy or better without even having to use my computer. Do you think this make web browsers obsolete? Will further advances in mobile technology lead to people not needing a traditional browser? If so, how can the browsers we see now be improved or optimized? We’ve seen things like google chrome and firefox emerge as the leading browsers. Where will they go from here?
