That is a fantastic bike, I have bike envy. Or I would do if I hadn't just managed to get hold of a 653 DY frame, one that is the right size for me, at last (and my previous one, which was too small) has just met with a nasty rear mech/rear wheel interface which means it needs fixing).
I am trying to decide if I go gears-inna-can or dérailleur. As Alfine/Nexus drop shifters are stupid expensive I think it will be dérailleur. I am going to use it as a light tourer, my Inbred 29er doing the longer/heavier touring load duties.
