The same for me, I love it for this sort of thing. I can bounce ideas off of it and it'll give me a solid response without getting tired of my questioning. And it'll explain in detail why I'm wrong. I really can't express how useful this is for my style of learning - I like to take things apart and figure out how they go back together.
This is exactly it, this sort of infinitely patient tutor dialog interaction is absolutely perfect for my style of learning and I can't help but be a little bit sad that I didn't have something like that available during school. That being said, I'm beyond thrilled to have it available now, makes it easy to never stop learning.
