A couple of months ago I saw this DIY charging stand:
What is a charging stand? Its a place where you can plug in all your gadgets for charging overnight.
If you think about it a "typical" family has lots of gadgets, say a mobile phone for every member of the family, mp3 players, gameboys, iPhone for daddy, portable DVD players, laptops, etc. Instead of having chargers lying all around the house I could see a dedicated charging station as a useful way to tidy things up.
As one of the comments to the above charging station points out all of the chargers draw power even when their gadgets are not plugged in, so it would be a useful improvement if the charging station turned off when no gadgets are connected.
