"Ubuntu Linux has millions of fans. What's not to like? A free
operating system with ten thousand free applications, websites
covering everything you might ever want to know, tutorials, active
forums, and more. Yet for all these benefits, situations pop up
when you want a faster, lighter operating system. Perhaps you have
an older computer, or maybe a netbook or a mobile device. Wouldn't
it be great to have a lightweight Ubuntu? That day has finally
arrived. Lubuntu offers a way to stay in the Ubuntu family -- with
a product that performs better and uses fewer resources.
"This article details how Lubuntu differs from Ubuntu. It also
compares Lubuntu to other lightweight Linuxes. It focuses on
Lubuntu 10.04, which is based on Ubuntu's 10.04 Long Term Support
release. (Lubuntu 10.10 is the latest release, with 11.04 due out
at the end of April.) Sample screenshots follow the article."
