One of the biggest advantages to using an Apple Mac computer rather than a Microsoft Windows PC is security. Macintosh computers are less vulnerable to viruses and other malware than Windows computers are. Mac OS is also more stable and cleaner than Windows.
There are disadvantages to owning and using an Apple Macintosh computer as well. First, Apple computers are generally more expensive than their PC counterparts. This difference in price is the main reason Windows computers are more common, which in turn is the reason they make an easier target for virus designers and hackers. In the end, however, the choice is one of personal preference.
