Despite all the detailed refutations (denials?), the main point here I think is pretty clear:

...some users are questioning the value that Nokia delivers through the N900, compared to other competitors or industry 'benchmarks' in this section of the market. (User's experience of the device, 3rd party support of the device, developers support, availability and activity of online marketplace, continued support thru OS iterations, etc, etc).

Obviously, many users overshoots their expectations of Nokia... and this is something that Nokia has to take some pride in that they've managed to do so(?). Although personally, I don't understand this, because Nokia hasn't had the track record to back this up in the past. But it's a worthy praise from the users, nonetheless.
