I'm looking forward to giving it a whirl. I interact with other humans when sharing and developing documents, so intercompatibility with the office and Office 2003 standards is literally the second most important thing for me, and all of the arbitrary also-ran file formats are a nice to have, not a need to have.

As evidenced by the fact that even the centers can't get on the same page about what alternative formats they feel should be mandated instead.
