I'm a new Mac user. I just bought a new MacBook Pro 13.3 about 3 weeks ago. I love it! The computer itself is very nice, I love the aluminum body and the screen looks fantastic. One of my favorite aspects is the smoothness of the look and feel of the operating system. The way the windows open and close, move around, and fade in and fade out. I enjoy using spaces. Also, some of the other keyboard shortcuts and Expose really make using a Mac a true joy. So why did it ruin the computing world around me? Well, as my Mac is at home I'm forced to use the Windows based PC machines all around me and at work. I didn't anticipate this happening. I was at work yesterday and I usually use the computer during my break. However, I didn't want to use it, I wanted to use "my" computer, my Mac! The thought of using the Windows machine after having experienced the joy of my Mac just didn't appeal to me the way it used to. I felt somehow disappointed, that I was "stepping down" to use the Windows machine. As if to use a Windows machine, I was lowering my standards. Anyway, that's how I felt. I really "enjoy" using the Mac. It's been a very pleasant experience thus far!
