Feisty -> Gusty, wait a month or two

It is about to be released, but now that I have upgraded two of them I
think you should wait.

It is extremely easy to upgrade, just a few clicks. But you may have
problems with the new Gusty. On my two upgrades and another I heard
of: all three had trouble with display drivers. All three are still
waiting for display driver issues to be fixed.

If you are running hardware that is a couple years old, you might be
OK. But I would wait a little while longer. It is that much different
from the end-user standpoint.
