Why, you ask? here's a good reason: the new president of a client company has a Mac. He always had a Mac, he loved his Mac and will not switch more that you will switch from your beloved PC. Am I going to say, man forget about your Mac we are a Windows shop here? I don't think so if I want to keep this job. What will I do? I will learn how to integrate his Mac to the system. By the way I suggest you start to learn this too, unless you are close to retirement. Mac are omni-present now, that you want it or not.
