Excellent point. While Amazon is unlikely to vanish over night, can your business really rely on it being there tomorrow? Even if it's still there you could be prevented from accessing it for a variety of reasons (billing, legal, technical). Do you have a plan for that? How fast can you recover from it? We're very careful about not putting all our eggs in one basket and have servers at two different VPS providers (Amazon-EU and Gandi.net in Paris) and backup (and only that) at a third. Our DR manual includes instructions on how to restore an EC2 machine to a Gandi VPS and vice versa.
