Don't bother with an IDE (Score 1)

Like editors, an IDE can be a very personal experience. Some people really like IDE's, some people don't. Some people like one IDE and not another. By teaching using an IDE, your going to hamper those who dislike/don't understand the IDE from learning the language. Just teach the language. Those students who want an IDE can learn it on their own. Those who want an editor with lots of macros will download them. Those who just want a text editor will use that. By teaching at the lowest common denominator, all students can learn as all of them will be able to go to that level.
