The different names for the same class across editions are slightly amusing to me. Since the focus of this challenge is "classic" D&D, I won't be naming the name they changed to when TSR was bought out. It's interesting that a lot of OSR bloggers seem to hold a great deal of nostalgia for the "magic-user" moniker, as opposed to the equally clear but shorter and more concise "mage".
Sorry this post is so short, but I'm trying to get it out before 12:00 so as not to miss a day. Work and play have left me dry, but I'm doing my best to stick to my promise (it's 11:58 local time as I write this)!
