According to Jyrki J. J. Kasvi's blog, the Finnish Parliament should start preparing for migration to Linux and OpenOffice. Linux is already being used for servers, and the next step would be to adopt the OpenDocument format for governmental communications.
The OpenDocument format has been in the news recently, now that StarOffice 8 is out.
Perhaps we will finally get out of the MS Word lockin and actually have some interoperability for office documents...
