MacOS lost me somewhere around Mavericks and the idea of a tablet that is also my PC was appealing, so I tried a Surface Pro 3 and decided to keep it. Ubuntu Bash for Windows is great, but is Beta and still needs some work. As for my old 2011 MBP, Ubuntu runs very well on it. For a couple of decades I kept trying Linux on the desktop, and today I am happy with it. From managing photos, CAD for my 3D printer, Python development and music with my keyboard, Dropbox support, it really is remarkable how far the desktop has come. I am still using the web client for OneNote though...
