Jim Rossman, who has written a personal technology column for the Dallas Morning News for the past 23 years, is leaving the paper. Rossman writes, “Back in the late 1990s, the Personal Technology section editor, the late Bob Bersano, asked me to start writing a weekly column called the Tech Adviser. The News had a great group of people producing a stand-alone Personal Technology section each week, and I was honored to be part of that group.
