Maybe somebody still remembers Nokia N9 from 2011. It was the first (and the last) Linux phone from Nokia and a very fine device indeed. That could have been the third platform, if it was let to live.
But soon after, an American CEO took control of the company. He had a clause in his contract that would grant him a big bonus if Nokia's handset division was sold. And of course, it was sold to Microsoft. And that was the end of Nokia. Sad!
