What do you know about the Mac (Apple computers)?

Before I read the class notes on the web page about the Mac, I did not know about it at all. Also, there are only few friends who have the Mac around me. One thing that I knew was the company of the Mac sells the iPod. However, after reading, I felt the Mac is better than Windows. On the class notes, it says Windows can get virus easily, and I agree with it. Now, I have anti virus software in my computer, but before I have spoiled a computer by infection of virus. Also, the anti virus software cost about 5,000 yen. On the other hand, in the reading says that the Mac computers do not have virus, and do not have to buy anti virus software! Both the Mac and Windows have many other good features, but I think security is the best feature to decide buying a computer. Therefore, I will consider about buying the Mac computer, when I buy a computer next time.
