I was reading my new issue of Popular Science this morning and found an article about X-Plane. It was a pretty interesting article. Along with information about the program and it's author, it compared X-Plane to FS2002.
The article is available online at:

Also, there is an online article about two Popular Science workers playing X-Plane and FS2002 themselves.
