A.That’s an interesting question. If you know the dealer’s reputation, the offer may be a good deal—and that may have less to do with your initial cost savings. Consider this: If a computer is going to break down, it’s likely to happen early in its life because of a faulty component. In fact, back in the 1980s, some computer makers and dealers “burned in” new computers for a day or two to filter out lemons. Today, however, with better-engineered components, there is little need for burn-ins because far fewer computers fail. But on occasion they still do, and the real cost of a breakdown is lost time and lost data. So buying a refurbished machine may not be such a bad idea.
