Microsoft’s Windows Phone revenue: $613 million, at the very most | The Microsoft Blog - seattlepi.com:

Buried deep within Microsoft’s annual report Thursday to the U.S. Securities and Exchange Commission is this little gem: In the company’s 2011 fiscal year, revenue for the Xbox 360 platform was $8.103 billion.

That’s not what’s noteworthy. What’s noteworthy is if you subtract that number from overall revenue to the Entertainment and Devices Division – $8.716 billion – you get a rough figure for Windows Phone 7 and Windows Mobile.

That number – which also includes revenue from Zune, Mediaroom, Surface and hardware – was a mere $613 million last year.
