Why do a lot of people say "Macs are just better for doing graphical design"?

Back in the late 1990s, I wouldn't work with anything but Apple computers for desktop publishing work and graphic design. Macs at the time were incredibly stable compared to PCs, had gorgeous display, supported a wider variety of fonts out of the box, had more accurate color depiction and seamlessly integrated many desktop and graphic design tools available at the time. Apple also made strategic partnerships with multimedia production companies and cemented themselves as a somewhat industry standard in the field.

Apple as a brand is seen as a 'set it and forget it'. This is how I felt and still feel about their products today. It attracted many creative types way back and now because of how simple and non-intrusive the entire system is with the latter being important to a smooth workflow.

Of course today, the divide between mac and pc is rather unimportant. They are both tools and whatever helps you do your work should be the one you use.
