As you can see from the KOffice 2.1 beta2 announcement (http://www.koffice.org/news/koffice-2-
1-beta-2-released/), there has been a lot of work recently on supporting at least .doc and .ppt. I
am fairly confident that .docx and .pptx will come as well. Excel compatibility was already quite
good. But, yeah, well, we certainly expect that the importance of binary or xml based MS file
formats will wane, given that many governments are moving to odt.
