Oh, another thing. Usually, after the software has been out for awhile, its not bug fixes that are being transmitted. It's improvements or added features of various kinds. Enhancements to the rendering engine, and so forth. It saves you from having to remember to check out their site to learn if a new feature has been added. A really good program will be in service for about two-three years before a completely new version is created. This is just a service the company provides you to keep your software up to date with minimal effort on your part.
