I ski, often in the company of some very good snowboards so don't think I have too much bias but...sometimes it is good to spot the difference:
I thought it was best articulated by a boarder I once met at Baker. About halfway up the chair he seemed to come back to consciousness then suddenly blurted out." Hey dudes I've finally figured out the difference between boarders and skiers. You like don't have any stickers or badges on your skis. Like how do you know where you bought your skis or like where do you to go to get your clothing? " Response "Badges ? we don't need any stinking badges."
Anyone able to come up with a better difference.
