It has always been a problem if you forgotten your charger from home. But now companies in U.S came up with the idea of one universal plug. This article talks about firms like Nokia, Sony Ericsson and other industry majors which agreed to back an EU-wide harmonization of phone charges.
I think this is a great idea and it will stop wasting so much resources to make machins for so many different chargers. Also now, if you just forgotten to take yours from home, everybody would have the same as yours. The article also ask a question if they will agree on one plug. Well, I heard that they already decided it to be mini usb plug.
There is also another asepect they didn't mentioned. Technology is improving so fast that we don't really know what kind of chargers we will need in few years so this idea would be good only if they would 'be on time' with new technology - wich is quite obvious they will. So now we can see that maybe they finded a solution for this problem but for how long?Will the circle reel? There is no way to stop technology from moving further.
