I suspect that Gene Sternberg knows a hell of a lot more about computers in general than do you.
"Gene has written over two dozen books on computers and the Internet, plus hundreds of articles for such industry publications as MacAddict, MacHome, MacUser, Macworld and Computer Shopper. He also writes a weekly column, "Mac Reality Check," for Gannett News Service and USA Today, and is a Contributing Editor for CNET, the world’s largest technology news service. His computer news and support Web site, The Mac Night Owl, receives thousands of regular visitors each day."
