Productivity is a subjective term, but essentially, it's a measurement of how efficiently a particular task is completed.

It introduces desktop elements like a panel, system tray, and so on, to the Fluxbox window manager, and is highly portable. It's a good desktop, and while it's generally easy to install, there aren't many distributions offering it by default.
