I can't believe that. At all. Nokia has a top-notch navigation program, a top-notch device... and they cannot put the former into the latter?
While they're actively advertising the n900 as an ovi maps-enabled computer?
Nonsense. Maybe they're looking which way it is not cracked too easily (c'mon - like on the symbian platform, you know, or like for navicore/wayfinder), but putting there a crippled version seems a dumb move to me. Maybe navigation is going to come as an update.

Otherwise, Rockerduck-like, I promise I'll eat my hat!
