What more could I want? Ability to import Access .mdb files, and comparable reporting. I haven't tested the latest iteration of oo.org Base, but what I remember would involve a complete re-write of our code.
We've got a few business critical apps built solely in Access. I am working on moving the backend out of Access and into MySQL, but the frontend has to stay in Access (Not my decision). That in itself is quite a task, as I'm re-writing all our code anyways, but my wishlist includes Access integration into OO.org.
As an aside, I use OO.org at home, on a Debian box, and find it more than sufficient for my needs.
