Does your system take time to start up? If you are fed up with waiting for it, you can use "InstantOn". It works like this. This software works a bit like an independent system of your local operating system. It can instantly start at your PC startup and offers you a few applications you may need when waiting for your main OS. You have at your disposal a Firefox browser (if you're eager to surf), a Rhythmbox to listen to your favourite tunes, and a messaging client, Thunderbird, and of course you will also have access to all your local data.
