As I posted here many months ago, essentially 4 quarters of royalties on Droids paid to Microsoft covered the entire purchase of Nokia. As I like to say "money for nothing and chicks for free". Microsoft is the gift that keeps giving. $50 now on the radar.
MSFT doesn't make money from Android. It makes money from harassing hardware manufacturers The hardware manufacturers have to pay "protection money" to the Microsoft mafia, so they won't get sued for producing Android devices. It's a shady offer the can't refuse. Remember when Microsoft sued Barnes and Nobel over the Nook? Barnes and Nobel almost went bankrupt fighting the Microsoft mafia in court, because they refused to pay the "protection money". Now most hardware manufacturers just pay the "protection money" because it's cheaper than fighting Microsoft's huge legal department with lots of cash.
your claim looks pretty high. what is it based on? ;-)
it also doesn't reflect the creative accounting used to cover up other losses. see if you can find this article:
"For the past few years, Microsoft reported the revenue and operating losses of Entertainment and Devices, which was the group that housed Xbox, Windows Phone, and those Android royalty payments.
That group always seemed to be profitable, but Sherlund says it's largely because of the Android money.
Sherlund says that if you back out the Android profits, Microsoft is probably losing $2.5 billion on Skype, Xbox, and Windows Phone. Of that, $2 billion in losses are attributable to the Xbox platform."
