Re: Difference between Q and Harry Potter wizards?
Potter Magic (And don't forget the House Elves have a different brand of magic as well), only the most skilled wizards can do wandless magic, and you can't just do whatever you want, you have to learn how to do spells, which involves the Wand as a focusing tool, and the words to make to happen. Yo have to feel the magic, learn the words (And in the caseof Potion brewing the recipes), have the right wand motion...
Sounds like "tech" to me at least with respect to the wands and potions.

Duckman: BEFORE THAT!!!
