Xubuntu is an elegant and easy-to-use operating system. Xubuntu comes with Xfce, which is a stable, light and configurable desktop environment.
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. It works well on older hardware too.
The latest Xubuntu distribution is Quantal Quetzal (12.10) and I use it heavily on my productions and will be my main linux box on every updates. The good thing about this distro is that its fast, cool theme, easy customization, and perfectly good for productions. You might want to look at its features here.
