The Nokia N9 UX Guidelines site is now up to date, so go have a look. We’ve also improved the organisation of the site to serve UI designers and developers better. Improved linking between the UX site and the developer documentation means that it’s easier to match what you want to do with how to do it.

However, the Chinese-language UX materials
have not been updated at this point. If you are using them, we’d like
to hear from you! Do you think it’s useful having some material
available in Chinese? Should there be more? Less? Different materials?
