None of this is to say that OpenDocument is perfect. Far from it. OpenDocument at present is crippled from an interoperability standpoint. I'm a member of the OASIS OpenDocument Technical Committee and I think the resistance of the big vendors to fixing the interoperability warts is simply outrageous, particularly because they are fairly trivial changes.
But the advancement of software users' interests are not advanced by painting OOXML as other than deeply flawed. It is vendor-specific and far from "open." The lesser of the two evils is clearly OpenDocument, which is at least open even if not yet interoperable.
The sooner folks can start discussing practical methods of convergence, the better. See e.g., http://ec.europa.eu/idabc/servlets/Doc?id=27956
That set of slides summarizing a conference of some 20 European national governments' IT types says a lot more about the future of office document formats than Mr. Asellus has to offer.
