OREANDA-NEWS.Microsoft founder Bill Gates called the company's main mistake the fact that it allowed Google to launch the Android operating system.

“The biggest mistake is my mismanagement, which did not allow Microsoft to become what Android is,” Gates said. Android is today a non-Apple universal platform, he added.

Gates added that an alternative to the iOS system would allow Microsoft to "become a winner and get everything." According to him, the inability to create it deprived the company of $400 billion.
