A guy on the Apple discussion forum started a thread titled, “Why do your Charger Cables have the lifespan of a housefly?” That question is probably enough to elicit a whole bunch of head nods from virtually everyone reading this, whether you’re an iPhone user, an Android owner or have virtually any device that needs […]

This is truly a golden age for fans of a big ginormous TV screen. Not too long ago, to buy a television over 40 inches usually meant wheeling one of those massive Mitsubishi or Toshiba projection monoliths into your home, consuming a vast portion of any room at a cost of potentially $7,000 to $8,000.
