So I just bought my Wii, and after letting my father try it he admitted that it was indeed pretty good (he had previously stated that Nintendo should go bankrupt, when I told him I was buying it[since im a uni student]).
Anyways, after playing, he saw the Wii on the vertical stand that came with it, but it was placed sort of near the edge of a table. And he asked why not put it down on its side? I replied "I don't know, everyone just had it up".
Is there any benefit from putting the Wii vertically other than make it look cooler? Because it makes a lot more sense for reasons of safety that it lies on its side.
