M$ makes big money from Android phones and tablets!
As George Kesarios, a financial analyst, explained in Seeking Alpha, the financial news and analysis site, "Android was developed using technology from many different companies. When patented technology is used in open-source projects, companies really don't go after them because usually they have little or no revenue. However, when an open-source project hits the jackpot, such as Google's Android, then the companies that control parts of the technology seek royalties, because these projects make money."
So, it was that "Microsoft has taken just about the whole space to court and is milking them."
And, how much is that exactly? Kesarios works it out. "While we do not know exactly how much money Microsoft makes on average from each Android device sold, the general consensus is that Microsoft makes about $8 on average,” he wrote. “If we translate that into dollar revenue, Microsoft stands to make as much as $3.6 billion in 2013 from Android royalties (I assume Microsoft is taking a cut from 60 percent of the 750 million Android devices that will ship this year, times $8 a device)."
