Creating web application for specific browser doesn?t really make any point.

I don’t understand what sense there is to make web based applications for specific browsers. Many web based apps works only on Internet Explorer on Windows machines. It would be much easier for developers just create special windows application to do that work instead trying to fork Internet Explorer to do that work. Just image a Content Management System that works only on IE on windows. Why not just create windows application with rich text editor or make customization into MS Word instead. I think Microsoft has a great API for writing nice windows applications but forking IE really sucks. This way perhaps there could be actually some use for Web Services as well. :)
