There used to be a lot of benefits when they used Motorola chips because they were true multi-tasking and more powerful, but now they use Intel single tasking chips (Intel/Amd chips use task switching to make it look like it's multitasking) they are no better than PC's, you just get way less for your money than a PC.
Most people buy Apple gear because of the styling, or they believe the hype. But when you compare what you actually get pound-for-pound, Apple stuff is just way over priced.
There are very good versions of the Apple OS that are fixed so you can install them on any PC. They work just as good as buying mac hardware.
