Last time I seem to remind Nokia was said to do things with M$ it was the time of one of the Communicators. Many many years ago. In the end they made a M$ Exchange-compatible app, or word- and excel-like apps.
Hope is something like that, something *innocuous*.

If Nokia turns W7, I'll buy another n900, used, just in case I lose or brick mine, and keep them until I find another device I can have fun with
