It's pretty obvious N950 is not a good option.
Given the previous history (I own 770, N810), it is highly unlikely this will be finished product when it get released.

I bought 770 because it was revolutionary.

Afterwards N810 came because there was no ready competitor at the moment.

When N900 appeared It was very well known it is dead, and there were already readily available competitors, so I've ignored it completely.

The community story is a nonsense, you can have a platform which is 99% open source, but 1% is more than enough to keep it closed completely. When you have a closed product, there is no effective community that can leave on its own.

As for the latest announcements, the picture was clear even before Elop announced the integration with Microsoft. The first sign to run away from Nokia was when Ari left the company.

Since I am not an insider I can only speculate. I would expect that the inner circle (of maemo project, not nokia as a whole) has recognized the situation much earlier than Ari's transfer. I think any reasonable person(within maemo) should have scrambled to find the position in other company after one of the leads have left uncompleted project.

In February it was already impossible to hide the truth, so the latest announcement is a gradual awakening for the rest of the crowd who is oblivious to the fate of this project/program. It's much like the boiling frog story. The poison is administrated in small doses.

Regarding the latest interview:
All those talks about ecosystem when comparing to Apple is ridiculous. Apple may have one major phone model at a time, but please bear in mind that latest iOS versions (I am talking about Major.Minor) are available for at least 2-3 previous models. That is the ecosystem, because major releases don't left out earlier models. Nokia has failed to understand that today the main game is not about selling the phones themselves - it is about keeping your customers to your platform (even the obsolete devices) so you can continue to deliver content.

From the Apple's point it makes more sense to keep the customer happy with the older product, than allow to switch to competition (now-days only Android).

So in a sense we can say that Apple is evil, uses fascists management methods towards developers and users, but at end it's them who are more "loyal" to the customer - they kept their crowd close together.
