As reported by drago01 on the mailing list - http://lists.fedoraproject.org/pipermail/desktop/2011-February/006931.html - the fact that Shell does not show icons on the desktop (by default) means the live installer suddenly becomes very un-discoverable. I'm not suggesting any particular solution, just flagging up the problem for tracking purposes. Proposing as NTH for Beta. (Not sure which was the best component to file this against, please feel free to change).
