When you went into a Boston Chicken and ordered quarter-chicken, white, with mash and corn, when that was rung up, that would signal all the way along the supply chain the need for more potatoes to be put on a truck a thousand miles away.

This is no longer a battle of devices, it is a war of ecosystems.

One of the changes I'm driving within Nokia is to adopt what we call 'the challenger mindset.' Let's understand that we have to fight, we have to fight our way through the difficulties, we have to listen to consumers, we have to both deliver what they need and also have some creativity and insight and deliver what the don't yet know they need.

If you look at the economics of Nokia roughly half of the company, half of the business, half of how we think about the business is focused on those emerging markets and on those lower-priced devices. But, of course, people who are aspirational and buying those lower-priced devices today are looking at smart phones tomorrow, and so forth.

The vast majority of people do not have, nor will they ever have a personal computer. They haven't been exposed to Windows or Office, or anything like that, and in their lives it's unlikely that they will.

Building on our successful partnership, we can now bring together the best of Microsoft's software engineering with the best of Nokia's product engineering, award-winning design, and global sales, marketing and manufacturing.
