Linux Ubuntu have really developed a lot during the last couple of years especially when it comes to user friendliness ;). I am my self running several Ubuntu servers with different types of open source software and it is definitely good and secure and I am really amazed how good a lot of that software is when it is originally developed by enthusiasts. However, Linux is far from the friendliness that is needed for a software in the consumer business like NCS. I agree that Windows 10 comes with a lot of extra stuff and has expanded, but in my opinion it also has a dramatic increased stability from earlier OS. Also, developing and supporting two OS platforms takes a lot of resources. Running a commercial business need also some income and therefore Windows is the platform. But, never say never ;).
Thanks for the input and keep up exploring Linux Ubuntu since it has its advantages. I will certainly continue and use it in favorable applications and user environments.
