I have 50+ instances on another cloud provider. The service cost benefit on going to a dedicated server is a fair bit but the management cost goes through the roof. We also prepay to save some expense on the monthly bill. I can easily manage those servers, spin up new ones as requirements change, drop ones I don't need anymore, etc with very little hassle. We also have a few dedicated servers(one actually with Xen on it for running smaller instances) and the time and effort to manage instances on it makes it pretty much not worth it for us without a dedicated sysadmin.
