One promoted benefit Software as a Service is that you are always up to date. There are no local applications to install and maintain. You don’t need to go through expensive and disruptive annual updates and/or install service packs or hotfixes; all this is taken care of for you. The latest and greatest software is always automatically available to you, and because everybody is always using the same version, there will be no compatibility issues. You won’t need to worry about your OS being compatible with the latest release, either. Bugs, if not exactly a thing of the past, will be quickly taken care of without you even being aware of them.
This is something you all want, right? What could possibly be wrong with this picture?
