I think 'ecosystem' is a euphemism for prison, it's the worst imaginable kind of vendor lock-in. I originally thought Elop was deliberately driving down the value of NOKIA so M$ could buy it at a knock down price and use NOKIA's extensive patent portfolio as a stick to beat Apple and Google with. As revealed by the defence in the Barnes and Noble case though there seems to be evidence to suggest Elop has already transferred thousands of NOKIA patents into a third party company in Canada where they are already being exploited to the benefit of M$. If this is the case it means an M$ purchase of NOKIA is probably no longer necessary, Elop will just continue to cream off any patents M$ want. It's hard to see where NOKIA can go from here, without their prime patents to protect them even if they dumped Elop/WP7 and went back to a high quality, high functioning OS Apple and Google would undoubtedly use their lawyers to give them a kicking. I'd be very interested to know what motivated NOKIA's board to go along with all this.
