Mac is for beginners, usually up to age 10, and for old people who start using computers. Windows is popular, so it's for people who want to maximize the number of programs they can use. It's more complicated than a Mac, but you get more out of it. Computer experts use Linux, which is harder to use than both.
The main difference between Macs and PC is the customization. The PCs are more customizable compared to the Macs. For instance, PCs have almost all their parts put in a modular manner such that, each part can be upgraded by its own. For the Macs, the device has to be upgraded at once for all parts. PCs are made by different manufacturers while the Macs are made only by Apple. Visit http://www.ehow.com/facts_4826071_difference-between-mac-windows-computers.html for more tips.
(Let me give you a thorough answer that is simple to understand. Be aware, I am writing this in a perspective of a Mac user and Mac evangelist who still has a respect for Windows and PCs. I am trying to be as neutral as possible, but you can tell I am more lenient towards Macs and Mac OS X)
Mac Mac OS X is the world's most advanced desktop operating system and runs on all Mac computers. Apple currently offers 5 models of Mac- MacBook Air, MacBook Pro, iMac, Mac mini, and Mac Pro. With the power of Mac OS X and beautiful hardware, Macs seamlessly work. In a sentence, The hardware and software were made for each other. A plus side to Mac is the amazing hardware Mac OS X was MADE to run on, and the security of Mac OS X. A minus side is the low customization level to whomever it concerns.
PC The term PC, or Personal Computer, often refers to a Windows PC, but can refer to a Mac, Linux PC, etc, but I am using it as Windows. Anyways, Windows software was made more towards the enterprise, business, and users who want flexibility and customization. But with Microsoft's latest offering, Windows 8, the consumer space was completely redefined and is easy to use. But unlike a Mac, hardware and software were NOT made for each other. Microsoft does not make the hardware and the software, rather the software is licensed to PC manufacturers. However, design in PCs are rather generic. A plus side, however, to PCs is the customization. A minus side is safety and generic computers.
Price- Macs are generally more expensive in price, but for value, Macs totally stack up. PCs range in price, but can sometimes cost less.
How do they compare?
The decision is completely up to you, but if you are a younger, creative person, go with Mac. If you are a business person, gamer, or in need of a less-costly computer, get a PC. My choice- Mac
