All the posts here are highly speculative, and many of them provide conclusions without rationale. I think one has to wait at least what the next two weeks bring before jumping to all these naive "I sell my N900" and "I hate Nokia" conclusions. Also, the blog posts that are cited here over and over again contain no reliable information. I'm sure more information on Nokia's strategy will leak over the next couple of weeks.

Here is my own speculation: Phones that are compatible to the new navigation application gained significantly in value, but their price remains the same. On the other hand, N900 has "lost" in value (relatively), because it doesn't have this feature (yet). I doubt that many people will still consider buying an N900 unless there is a definite statement from Nokia that they will bring the advanced navigation features to that device. Therefore, I believe Nokia has two options:

(1) Announce similar navigation features for the N900 soon.

(2) Not care about future sales of the N900.

Everything one reads in the press about the surprising success of the N900, the dual platform strategy (Symbian for phones, Maemo for PDAs), and the fact that Symbian is not considered competitive with other smartphone OSes indicates that (2) is not an option.

So, here is my prophecy: Within the next two week there will be an official statement that similar navigation features will be made available for the N900 "soon". Not sure what "soon" will mean, but I'd hope within the next 3 months or so.
