Electronics manufacturers have never been known for being environmentally friendly (and neither are consumers of their products), but it’s nice when a company takes the initiative to make its products more energy efficient.
Sony recently made its PS3 33% more energy efficient and includes controllers with rechargeable batteries in each system produced. Nintendo on the other hand requires you to use batteries with each Wiimote, unless you buy a third-party product. Nintendo also packages its controllers and peripherals in unnecessarily large boxes. Consumer lawsuits are partly to blame for controller skins, but Nintendo could at least package them in reasonably sized boxes. Oh, and they might want to stop encouraging useless 24/7 connectivity too.
