In my office, I have more than a dozen AC/DC power units for a variety of electronics devices ranging from cell phones and MP3 players to radios. The problem is most of them are totally useless because the devices they're supposed to power have been lost or been broken. And if I still have the device, the power unit has been lost or its broken. How comes the consumer electronics industry can't create a single standard for power units - a one size fits all approach? I mean, if the high-tech industry can agree on USB standards, you'd think something as established as electrical power units would be a snap.
