Most comparisons of the KDE and GNOME desktops focus on usability and productivity apps. However, they often neglect what might be called the leisure apps -- specifically, those used for image and music management.
But in the modern online culture, these leisure apps are often as important to users as any other aspect of the desktop. For many, especially at home, they are probably more important than a word processor or spreadsheet.
In KDE, photo management is generally handled by DigiKam, and music by Amarok. In GNOME, F-Spot is used most often for photos, while traditionally Rhythmbox has been used for music.
More recently, however, GNOME-based distributions like Ubuntu are discussing the replacement of Rhythmbox by Banshee, a more full-featured application.
How do the apps in each category compare? Answering that question not only serves as a consumer's guide, but reveals some of the development trends in KDE and GNOME.
