thanks for the awesome comment.
in addition to that;
- many ethical hackers, penters prefer linux because it's open source, most of the hacking tools are free and most of our server is unix/linix based.
- many developers, graphic designers, animators prefer to use Mac because it has sufficient capacity to hold softwares like photoshop, maya, autodesk etc
- windows is the most popular operating system because it is low cost and can be ported to most computers machines/products such as Hp, Asus etc unlike MAC
