I think MS is very worried about how popular Android devices are now.

So they are, like you said, giving Windows 10 away for free.

There is even a proposed version of Win10 for the new Raspberry Pi model 2.

So that tells you something about the popularity of the RPi and Rasbian that runs on it.

It is the most successful computing platform GB has ever known.

If people get used to Android, it's a very short step from there to good old Linux.

There are so many windowing systems available for Linux it isn't even worth counting them!
