As the average end user, yes one key difference is that the system can actually run one of the three applications that you use on a daily basis. We also allow the user to continue using a file system that she is comfortable with, making adoption easier. Other differences are by design transparent.

From the perspective of a more security aware user, they will immediately notice that their data is cleartext _only_ when they are using it locally and only they have the capability to access their cleartext data.

As a developer, you may appreciate the underlying integration with your system. But this of course remains to be seen (as others have pointed out, we have not yet made any code public).
