No shit, sherlock. Anyone with an ounce of sense would wait, oh I dunno, maybe ONE DAY before updating, to avoid 99% of the traffic and potential issues? Otherwise, you have no right to complain. No, everyone needs iOS7 THIS SECOND, after waiting for months. You will live if you go another day with iOS6.
...but...if everybody with an ounce of sense (and they must have an ounce of sense, because they're buying an Apple product, right?) waited till day two, day two would be just as bad as day one! ;)
