Although both SaaS software and the AccountEdge Hosted cloud desktop are both provided from a cloud based data center, SaaS is a specific software on the cloud accessible via a browser. With AccountEdge Hosted cloud desktops, your desktop is hosted within a data center with AccountEdge and other applications pre-installed. You'll be using the software that you are accustomed to on your local computer. Think of this as having a PC in the cloud running Microsoft Windows which you can access from most any device from any location.
