Stable

Ubuntu is built upon the legendary stability of the Debian GNU/Linux operating system. Wave goodbye to crashes and freezes and say hello to a reliable system which just works.

The reason for the stability of Ubuntu is the way in which it is created and maintained - if someone finds a stability problem in an Ubuntu application, the problem can be reported and fixed ready for the next release, which will be available within six months. No waiting for service packs, just a working, rock-solid system at your disposal.
