I use it to build VM on demand using the elastic resources offered by cloud. It's very easy to use, fast and reliable. The interface is simple without adding unnecessary buttons or menus. The only thing which could be improved in the future would be related to the pricing. Sometimes you get services that are not really worth it (like a full disk space, CPU or memory for instance). But it's just a matter of time before you realize what you're getting and decide whether to continue or not. We use it for building VMs on demand so we have no need to purchase dedicated hardware to do this.
