Xubuntu is a community developed operating system that combines elegance and ease of use. Xubuntu comes with Xfce, which is a lightweight desktop environment that aims to be fast and low on system resources, while still being visually appealing and user friendly. Xubuntu is perfect for those who want the most out of their desktops, laptops and netbooks with a modern look and enough features for efficient, daily usage.
Xubuntu 14.04 is a long term support release, so the focus is really on stability and finesse, not on adding tons of new features. Xubuntu uses the Xfce desktop environment instead of Unity, Xubuntu can be particularly useful if you have an older or otherwise underpowered computer.
