This is great!  D will likely prove to be a massive productivity boost for
Nokia developers; I'm sure this will eventually be the case even with
third party developers working on Nokia-based projects. 

It would be great if we could get tango working on
this device at some point, as well. Feel free to drop in on the irc chat
groups #d and #d.tango (freenode) where you'll likely get all the realtime
help you need.

All the best!
