Microsoft earned 3 times the revenue from Android than from Windows Phone 7 in Q237
1.4 million Windows Phone 7 units sold from which Microsoft received a $15 license fee on each phone. At the same time, the company brought in $60 million from the sale of 12 million HTC Android phones from which it receives $5 in royalties for each unit sold. The analyst used Canalys' Windows Phone 7 sales estimates and HTC's own statement that it shipped 12.1 million handsets in Q2 (although it is not known how Dediu figured that they were all Android models).
While the amount of money involved isn't that important for a multi-billion dollar company like Microsoft, just the idea that the company's fortunes were improved more by a rival mobile OS than from the firm's own home grown software shows just how inbred the whole mobile OS business has become thanks to patents, royalties, licenses and lawsuits.
