It's the end of FOSDEM - it's been great. More on that later.
Meanwhile, I'm sitting in the hotel lobby at 11:30pm, and some random businessman starts talking on the phone to a colleague about his problems opening a ".docx" file. Apparently the converter won't install on his Mac, so he might not be able to get this work done until Thursday.
I happen to be wearing a bright blue OO.o 3.0 T-shirt today. So... I walked over and suggested he try it. His colleague on the other end of the phone was a technical guy, and had heard of it.
It took a 20 minute download or so, but Microsoft OpenXML works out of the box with OpenOffice.org 3.x - and apparently looks nicer on Mac OS X than it used to. Another satisfied customer!
