Correct me if I'm wrong here, but it seems all wizards and witches need
wands to perform magic...

...except Harry who inadvertently performs magic whenever he loses
control of his temper ie. releasing the snake and inflating the aunt.

Anyone besides me see this as a crucial point which will be elaborated
upon in future novels?
