I would not have been able to take the course otherwise. The laptop I received was set up with Linux Ubuntu. I would have loved to use it, but I did install Windows for the Nucamp fundamentals course. You are allowed to use Linux but they can not guarantee support for it. They support both Mac and PC. I was glad I didn't try and learn Ubuntu and the course work...actually I did try and it quickly became apparent that this was not the time to learn both! The class was more than enough and required my full attention. It was brilliantly packed with relevant learning material.
