Web desktops - do you find it interesting?

Question

As a win32 developer moving into web deveopment the last few years, I found the
web desktops based on extjs very interesting.

Coolite Desktop (broken)
Ex

Answer 1

In my opinion but people will never use them as a desktop replacement, there are too many quirks and potential pitfalls to be an actual replacement or even useful.

They do make an cool demo of ajax-y technologies and serve as a guide on how to develop apps with that desktop feel (which I'm not sure it's worth it), but not much more.
