我仔细看了一下季报和网上的消息，smart phone 6.6M，其中WP7 1/3， Symbian 1/3.
所以WP8卖了2M左右。
在美国70万smartphone, 应该没有Symbian. 所以WP8应该占一半，35万。
关于微软的部分：
Our agreement with Microsoft includes platform support payments from
Microsoft to us as well as software royalty payments from us to Microsoft.
In the fourth quarter 2012, we received a quarterly platform support payment
of USD 250 million (approximately EUR 196 million). Under the terms of the
agreement governing the platform support payments, the amount of each
quarterly platform support payment is USD 250 million. We have a competitive
software royalty structure, which includes annual minimum software royalty
commitments. Minimum software royalty commitments are paid quarterly. Over
the life of the agreement, both the platform support payments and the
minimum software royalty commitments are expected to measure in the billions
of US dollars.
Over the life of the agreement the total amount of the platform support
payments is expected to slightly exceed the total amount of the minimum
software royalty commitment payments. To date the amount of platform support
payments received by Nokia has exceeded the amount of minimum royalty
commitment payments to Microsoft. Thus for the remainder of the life of the
agreement the total amount of the minimum software royalty commitment
payments are expected to exceed the total amount of the platform support
payments.
意思是微软给的钱以后要以license royalty的方式payback. 现在从微软拿的钱多（
250M/q），以后（不知道多久以后），要倒找微软了。如果这几个Q没给微软钱的话，
如果量上不去的话，以后会变成沉重负担。
