At least for instant information and such. And the n800 is a very useful device in its own right.
While that device looks very cool, I don't think it's supported enough with minimal tech people who are working on the software. I would wait until it has a larger forum membership and for them to clean up all the bugs. Maybe when version 2.0 is out.
