Xubuntu
The only difference between Xubuntu and the other Ubuntus is the XFCE desktop environment, the key advantage of XFCE over Gnome or KDE being that it is lighter and faster, which makes it particularly well suited for older or low-end computers. As a lightweight desktop, XFCE does not pack all of the features for example of the KDE desktop, but it comes surprisingly close.
Xubuntu actually uses the 4.3.90.1 beta version of XFCE and still has a few rough edges, which hopefully will be smoothed out in future releases. Read more.

Other than saying the same thing as on xubuntu.org, how is this “helpful”?
