... because of this story reported by CNN. In a victory for the environment, consumers, and common sense in general, cell phone manufacturers are pledging to move entirely to a common micro USB charger standard by 2012. This has been a long time coming. I can't tell you how happy I was to find that my new phone used the same micro USB plug as my old one. I happier still when I got to return the new travel charger I'd just bought to the Verizon store.
Of course, cell phone companies will just roll the profits they were making off of these accessories into the price they charge for the handsets themselves but at least we'll be throwing away less obsolete electronics this way.
