Oh, I can think of quite a few things. Reading lamp by the bed, desk lamp, computer, possibly printer, charging cables for [Handy/IPad/Notebook], CD player, TV, game console, night light, string lights for Christmas, heater during baby age, vacuum cleaner... But of course, if the budget is limited, you have to make compromises. We used to do that with additional triple sockets (and I’m not going to say how many of those I currently have in use in our rental apartment). But at least in the living room and kitchen, I wouldn’t want to do without plenty of sockets. And who knows what developments and great new devices will come in the next years.
