Does it really matter that the LCD TV has a contrast ratio of 40,000:1 or that the digital camera has a 12-megapixel resolution?
David Colker gets to the bottom of these befuddling questions ahead of the holiday shopping season. He offers an in-depth gadget guide that doesn't make suggestions about what to buy but about how to buy.
