There has been no firmware update for the ADP1, but one is supposedly in the works. In all likelihood, all that's needed to access paid apps is an updated Android Market application. The holiday bonus firmware quite probably has an updated market app, and thus works.
If that's true, this article is completely alarmist. I won't believe the ADP1 can't access paid apps until I hear it from Google itself.
