A COUPLE of weeks ago, I replaced my three-year-old BlackBerry Pearl with a much more powerful BlackBerry Bold. Needless to say, I was impressed with how far the technology had advanced in three years. Even when I didn’t have anybody to call or text or e-mail, I wanted to keep fondling my new Bold and experiencing the marvelous clarity of its screen, the silky action of its track pad, the shocking speed of its responses, the beguiling elegance of its graphics.
