A rough estimate of the number of HTC Android devices shipped is 30 million. If HTC paid $5 per unit to Microsoft, that adds up to $150 million Android revenues for Microsoft.
Microsoft has admitted selling 2 million Windows Phone licenses (though not devices.) Estimating that the license fee is $15/WP phone, that makes Windows Phone revenues to date $30 million.
