Updating to Gutsy

Really, I think Ubuntu is (for the moment) the best Linux desktop distribution. I am an Ubuntu believer from the beginning of the times :)
Recently I have upgraded my laptop from Feisty to Gutsy Ubuntu distro. Really there is not much say, simply put Ubuntu CD or upgrade from update manager.
I only want to note two point here:

• Restricted formats, and
• Medibuntu, for multimedia formats.
