I bought it. I don't like the way it looks in iPad, with the column on the right side that's cut off. I also feel like I should be able to swipe to view it, instead of just pressing the arrow at the bottom. But, otherwise, I like it and I think I'll use it to brush up on some fundamentals. PS, add Ruby!
