PCs are tools, and Macs are appliances.
Fundamentally, when Apple designs a Mac, they’re making a device that looks like a computer but is targeted at very specific use-cases. At one point, it was the “digital hub” idea. Now it’s added a “internet client” flavor. Their high-end stuff is arguably targeted at content creation.
In any case, Apple is not building you a general purpose computer. They’re building you an easy to use, reliable, low-maintenance solution to your problem. An appliance. Arguably, the part of their product line that is dedicate to general purpose computing is already declining in significance.
PCs on the other hand, are really more about delivering technology. It’s about getting you the best hardware for the best price. Windows (and Linux), while having some built in features, is about providing the platform that allows developers around the world to target all use-cases.
Interestingly, the world needs both. Kindles. Chromebooks. iPads. All are examples of use-case specific devices that provide a lot of value. Appliances are all around, and their simplicity and reliability provide value when you don’t care about the details. Tools are around too and are just as important. Not everybody needs them, but they can provide multiplied value to those who can utilize their flexibility.
Appliances make your life better and easier. Tools help you create the future.
