Have a muck about with it. If you are the type that just 'gets' computer programs, you will do fine. If you just don't seem to get on with them, you will want some training. I thought that the tutorial was more than sufficient for me learning about the program. But I tend to pick up computer programs pretty quickly.
I personally don't like it all that much because it puts me out of my comfort zone of how to do the coding. I found I was paying too much attention to the leaves and trees and not enough to the forest. However, I think that is more a personal mental issue I have. Give it a go and see what you think of it.
Because of its ability to group and put out some easy-to-read information about the codes (nodes in NVivo), I will likely copy the coding into the program as one of my iterations/checks of codes. Then I can let the computer do what computers do best (I hope).
