Is Linux Desktop too radical?

In the past 18 months, GNU/Linux desktops are undergoing radical innovation: KDE 4 has released a bunch of new features, GNOME announced the launch of a new desktop, and Ubuntu launched a design competition, the first announcement is the "Notification System ".

A series of Innovations obviously won't stop in a short period of time, but a very basic question is: does the desktop user experience change whether ordinary users buy or not?

Innovation shows the vitality of open-source desktops, but feedback shows that innovation is not favored by users. For example, most users think KDE 4 is not as good as KDE 3.5. GNOME Shell of the new GNOME Desktop is also condemned, although no one can clarify the final form at present.

Free Software is still driven by developers. In the past, developers were software users. However, as the user base increases, the developer-user situation has become a distant past, however, this habit persists. The result is that the developer's focus on features is too far away from what the user wants.

The solution may be more tests and testing is a time-consuming and expensive process. Therefore, most open-source projects ignore it or perform it in a small scope.
