Yep.

Freedom.
By storing the data separately from the UI, I can make changes to each
without affecting the other.
In the old HyperCard days I used to store data in fields, but then I had
to ship a new version with a very different interface, which meant
writing a complicated export/import routine, and encumbering the user
with having to run it before they could use the new features.
These days, with the data stored separately, I have the freedom to add
anything I want to the UI, and when the user gets it their old data just
opens up in without any extra effort on their part.
