I've been using both OSs for over 20 years and the ONLY reason I use windows is for CAD (just 2d). All the foss options have potential but are very poor options for a longtime autocad user. Wine implementation is currently broken/terrible. VM is sorta a fallback option but doesn't run as fast as a native windows machine.

I plan on switching to Librecad or something similar but it's like a 10/20 year plan and something tells me I'll have to develop the features I want myself.
