Again 5 stars for the policy of Nintendo, the power supply for sale separately. From my perspective, I can say to that is: I have three children and each wants its own Nintendo. Before, I had to pay for three power supplies, even though I only needed two. Today I only pay for the power supplies that I need. I find it good. Saves money and avoiding electronic waste. One can also cause so look around.
Another example: I am annoyed when buying a new PC or monitor each about the equipment included power cord. I'm using for 25 years at home computer and I can not count how many power cords I have thrown away in time. A pointless waste of money and copper. Luckily there for a few years Recycling Centres for recycling electronic waste. Why any device network cables are included? If there really are people who buy their first device and have no power cord at home, Let them buy one this, but please, dear producers, puts the equipment at no power cord.
