Why is DNG better than proprietary RAW formats?

A lot of camera companies have RAW formats that are specific to that brand. Not only does it make interoperability a pain, but often these files are not really very well constructed and require an extra file to accompNy them in order to see any of the non destructive editing. Enter adobe’s DNG file format. DNG is an archival open standard which in addition to providing a 15-20% smaller file size, also contains any edit data within a wrapper so that it’s always accompanying your image. After I get home from vacation I’m going to convert all of my RAW files.
