Like millions of Americans, I find myself at a digital crossroads. I nervously eye reports on whether or not the U.S. Congress will delay the switch to digital television. More locally, I consider the fate of my older, 20-inch living room television set with its charming rabbit ears and snazzy, newly installed digital converter box. Among the questions I’m considering are whether or not to put aside my spiteful attitude and sign on to a cable or satellite service, or purchase a digital-ready set.
