I have never had a nokia device that had many incremental updates whether it could do it OTA/network or not. I am not sure where you are coming from with that statement. Even as this device is starting to be released we already know there will be no more updates to Diablo, and I am sure once the details of the Maemo 6 device next year are released you can kiss goodbye any hope of any more updates to the maemo 5 on your n900. This is not necessarily a negative to me, just a fact of how they have proceeded with maemo development thus far and I don't see any reason to think 5 will be any different than 4.
