Intel Macs and CAD

just curious, becuase i’ve never been a mac jocky, what’s the draw? i know all of the graphic designers i’ve worked with won’t use anything but a mac, but i’ve never understood why. all the adobe sofware is available for PC too. Solid Works Doesn’t crash on my wondows machine, Rhino runs great, Im not running a double OS so i have plenty of ram for big assemblies and rendering…what am i missing out on by not using a mac?
im always asking why?
