The next time you find yourself in the COEX Mall in Seoul and you find one of your screws is coming loose in your handheld or you need to give your screen a quick cleaning and dare not take your t-shirt to it, check out one of these Service Zones. As you can see, there are also lockable cabinets where you can get your DS (and, we assume, DS Lite) charged while you're shopping.
Apparently, the idea extended from similar areas that offer the same kind of services, except for cell phones. If you ask us, we'd like to see this extended to other territories. Namely, here.
