We have a dedicated "charging cabinet" in our living room for laptops, cameras, DS's and the like, but, we keep our cell phone bedside at night. Aside from the fact that we read books on our kindle iphone app, we also use the alarm and have been known to check emails first thing in the morning (bad!, I know). At Home and Housewares, we saw that Oxo makes a nice item to help out with keeping charging neat in the bedroom and beyond.
It is a charging station with a built in cord control system. Simple, helpful and neat - perfect for small spaces.
