Maemo marketing, has waxed official about the N900's release and quite casually noted that it'll "start shipping during November 2009," which as you very well know is a whole month later than originally expected. An interesting tidbit to his post is that he notes Nokia had lent out 300 pre-production units to the community, and he stresses the importance Nokia places on the feedback received. Connecting the dots might suggest that feedback wasn't quite as hot as Espoo had hoped, and a few last-minute refinements are now being applied. Either way, you're gonna have to refill your patience for potentially another month of waiting.
