Chargers are one of these things I never understood, what they were thinking. Nintendo stops shipping their handhelds with a charger, stating everyone would already own one and on the other side, every other company has their own homebrew chargers which just stack up at home, because they are specifically designed for that one device they are shipped with.
I just wish, they all would just decide on one standard and go with that. You could buy a Vita and use its charger to charge your 3DS, for example. That would solve the "cables everywhere" problem relatively easy, while keeping the possibility of not owning the charger but the device at a minimum.
Although, it would be really interesting to hear, how many people bought the 3DS XL along with one of a gen 6 game, just to rage afterwards, because they realized that they still needed to wait longer before playing the game, because they still needed a charger. {XD}
