Very good piece of news for mobile customers. All manufacturers of handsets have agreed to standardize the charging socket. That is excellent.
The consensus happened at the Mobile World Congress some time ago!
In fact, I have been asked many times by people, why do phone companies do this? There was a lot of merit in the argument for standardization. I guess the only reason this took some time was because the industry is so young. It takes time for such things to happen. Many times, an incumbent in position of strength is not willing to let go. Other times, the companies are simply not talking to each other. Forum's like the MWC are helpful in such case.
I am sure it took longer to standardize usual electrical wall sockets. In fact, even today in India the usual 5 Amp socket comes in 3-4 sizes. Either the width between L-N holes is too small and your cannot plug the pins in OR the diameter of the socket is so large that the pin just falls off...
With mobile phone makers being limited, at least we can be assured that customers don't have to put up with such nonsense.
