There are web document editors, web photo editors, even web audio editors, yet the general conception is that the desktop is the only place for ‘serious‘ applications. That is gradually changing and one thing that will help is the work carried out to bring native 3D graphics to the browser. One very interesting project is WebGL, which is shaping up nicely. WebGL is intended as a standard and it has now won another victory on its way of becoming one. Google has decided to stop development on its O3D project and start focusing on WebGL.
In the meantime, WebGL went from a project proposed by Mozilla to well on its way of becoming a standard. It is supported by all major browser manufacturers with the sole exception of, who else, Microsoft. Internet Explorer has never been much of a fan of standards or adopting new technologies. The fact that WebGL has OpenGL underpinnings, which competes, in a sense, with its DirectX offering on Windows, makes it even less likely that IE will get WebGL any time soon. Luckily, Google provides the Chrome Frame.
