We are a mobile society aided by the inventions that we design engineers have helped create. However, if you take a closer look, the underbelly isn't very pretty.
"Excuse me; are you going to be long?" -- that's the new mantra for those of us who travel and find ourselves waiting in line to get some juice for our starving portable tools. We have our new brains in the palm of our hands and they can help us keep in contact, look at spreadsheets, write articles, solve design problems or even relax with a game or movie. What good is it if all we are doing is looking for our next fix -- the next infusion of AC-juice to keep us going? We have crossed that line where we no longer have the battery power to keep our multi-media devices going for a day's use.
There are others out there in the ranks of the consumer who also hold this opinion that we need too many power converters for too many portable tools that don't last long enough.
I know what you're going to say " "look at all the portable electronics shows that say we are very close to having the designs that can provide full-day compute time and thus, less need for the jumble of wires and wall warts." But this isn't a game of horse shoes, where close counts.
Finally, we need one converter that works for all portables and all devices at the same time. I have chargers for my phone, my digital camera and my laptop, and it would be really helpful to charge all of them at the same time with the same charger. How many charging units do you have, and how many portables do you have to charge everyday? Are you one of those road warriors schlepping all your wall warts around only to stand in line at an AC outlet to get some juice for your portable brains? Me too.
