USB charging

Recently, there is more and more devices to support re-charging via a USB socket, this is a very good sign indeed. Currently, I have two MP3/MP4 players, two mobile phones like this. And better yet, some even share a cable with the same sockets. That's really convenient.

Convenience is a factor, but the other concern is environmental protection. We have so many chargers or transformers at home, to dig out which one to use is wasting time, it's also hard to organize, and then since most of them are proprietary, you will never be able to use them again in your future devices, so they ended up in the rubbish bin even if they're still functioning properly! Worst yet, you have already paid for it, both for itself as well as the environmental price!

So, I suggest all of you when you buy a new digital product, other than looking at the functionalities and features, price, etc... look at its charging interface, give priority to those which use a standard interface like that of a USB! That helps yourself, as well as to protect our lovely planet Earth.
