Just ran across this by accident and thought I'd post it here to see what you guys thought. What if apple was to start to use green plug in their new products? Green Plug is a Universal Power Adapter that uses a chip in the power cord that is plugged into the green plug adapter and adjusts the voltage to the preset chip. This means one power cord for every product and no power brick. If you take a look at it from a futuristic approach Green Plug could make a power outlet that could eliminate the adapter and could eventually become a standard for homes. Green Plug not to mention is extremely environmentally friendly!
Here's a link to a demo of the product: Here
Well, according to Apple's way of doing things, I would be very surprised to see something like that. I would love it, but it seems that Apple just goes the other way around, designing things specifically for each model. Not only the chargers, but look also at the external DVD unit they made for MBA that only works with MBA.
