DNG is just a container format (a glorified TIFF) to store the RAW data.
It's not the most space efficient, but with the low cost of mass storage today, it's not really an issue.
If one wants to have universally accessible files (esp. in the future), DNG is better than any proprietary formats.
It also allows one to use older software versions without being forced to upgrade (as in David's case).
