Smart Tray: Lamp + Charger + Speaker

Quite a lot is at once the Smart Tray can, to be Sang Hoon Lee has come up with a concept: he invites all possible gadgets via USB to (or by induction), serves as a mood lamp, whose light can be dimmed at will sonicated the room with attached speakers on the sides and generally serves as a repository for things that you otherwise rather postponed.Individually, there are all the functionality  already, and it would therefore not particularly complicated to pack it all in one device, which I then have question where to establish it best. In the hallway? On the desk? Or, maybe even hang on the wall?
