Mac OS X is commonly used by artists and musicians, as it has fairly powerful inbuilt tools for image, audio and video editing. It also has an inbuilt security system to defend against viruses. However, it is noted that it is not as good in customisation, price point, and versatility, as few programs are written for Mac OS X unlike Windows, and the actual computers are near-impossible to upgrade in some areas, mainly due to the aluminium 'unibody' design of many of the computers.
