The N90 has it’s own blog, The NSeries Blog
It’s not clear whether it’s actually Nokia behind it. (I don’t think so)
But it’s a clear example of how a product could have a blog to promote it self.
UPDATE: Nokia is behind the site. Andy has left a comment (below).
Nokia is behind the site. My agency, Comunicano,Inc. was hired to develop the concept of how to work properly with bloggers.
This is part of a new program called Blogger Relations Communications, hence the sites name, BloggerComm.com
