Silly ass - it's a war of phones.
When Apple stuffed Nokia with the iPhone back in 2007, it didn't need an ecosystem. It just needed, Steve Jobs, Jonathan Ive, the Apple team and a fantastic phone.
No one else. No ecosystem.
CEOs like to talk about things like ecosystems because it's something they can influence. They like ringing up other important CEOs and discussing hook-ups.
When what they should really be doing is figuring out what people want from the next generation of mobile phone. But, for CEOs, that's difficult work. Down to earth work. Work that's probably beyond them.
So the CEO babbles on about ecosystems while Nokia's stock exchange valuation falls by $7.7 billion in the two days after the announcement of the Nokia-Microsoft hook-up.
That shows what the market thinks about ecosystems.
