Very true.
But it has little to do with PCs themselves, it's just Windows doens't natively support color calibration. It's not their responsibility. It's the responsibility of the monitor/graphics card manufacturer, and it's Apple's vertical intergration with all it's hardware and software that allows Apple to sell it's products. Apple is first and foremost is a hardware company. Apple makes software, like colorsync, to sell their products. Which is also why you will never see OSX and FCP for Windows machines.
Color is very important to the design industry and although Colorsync is a bit complex to fully understand, it's not completely out of grasp.
