Exactly. With Nokias track record of support it is the open-source nature of the N900 that makes it so promising.

If Nokia do their usual trick of not delivering what they promised, there is a reasonable chance someone will hack the feature in anyway.

Also I can't see them ditching the N900 quite that soon, as the 5800XM is still getting firmware updates and that has been out a while now.

They are also at serious risk now of of alienating all their fans, as they release buggy after buggy device. Granted, the N900 doesn't sound too bad but people will see its feature-incomplete state is the same as a buggy device. So unless they add the functionality to the N900 people expect (or the community does), who is going to trust them on their next device?
