When was the last time you used netscape? I've found that Netscape, Mozilla, and their little brother Phoenix are all superiuor to IE.
With tabbed browsing, site-selective image, cookie, and popup blocking, instant access to font resizing, and other great features that are a part of the Mozilla codebase, it looks more to me like microsoft is sitting back and taking it easy.
Netscape/Mozilla is more secuire, more robust, and generally an all-around better product in every way. I guess some people don't mind annoying popups and similar stuff as much as I do.
