I did some wok cooking at a noodle house years back, and I can tell you three things:
1. It's a lot of fun.
2. You need a lot of heat (more than most conventional stoves can produce) to keep a wok hot enough to work its magic.
3. As
@Brute said, prep is essential. Things go fast (like, really fast) when things are going right, and if you have to walk away to get something or chop something you forgot, it can ruin you.
I currently do not have anything close to a proper wok burner on my stove, and that makes it difficult to near impossible to maintain sufficient heat on the cooking surface to properly execute a lot of wok dishes. I also don't have any safe place to properly season a wok. To compensate (somewhat), I use a cast iron skillet to make most of my stir fry dishes. It isn't a wok, but it holds what precious, little heat my typical, cheap-ass stove can muster better than a wok, so it works better for me. If you've got a good burner like
@Evan B , you should rock the wok!
