Pros
Pro Fast
Programs open noticeably faster with ROX Desktop than with most other Desktop Environments.

ROX can be built from source like many other solutions or can be installed from official packages available for all the major distributions (Debian, Fedora, Gentoo, openSUSE, Mandriva and Slackware).
Pro Singular load/save dialog
Instead of learning and navigating a multitude of file dialogs, simply drag and drop files between your app and your folders.
Pro Superfast
Pro Rich set of plugins
Pro Extremely lightweight (120 kb)
Pro Unique navigate-as-you-type mode

Cons
Con Discontinued
discontinued since years, only the filemanager, the terminal and zeroinstall are still developed
Con Very ugly UI
Con Redundant default configuration
Because speed is one of the main points and objectives of ROX, the default configuration can be redundant for some and it's design also makes a lot of assumptions on how users prefer to work.
