It’s more than just a slogan from an old commercial. And while arguments over the respective merits of the two main computer types have a tendency to get out of hand, it makes sense that some feel so passionately about the subject — many of us spend most of our day on the computer, using it not only to get our work done but to keep in touch with loved ones. The differences between the two really are substantial, with Macs often thought of as being more user-friendly and PCs having more power. Whichever you prefer, at least you get to type your response the way you want to.
