The sale process & rationale for education and tools is very different from fiction. With a few exceptions, it's much easier & powerful to sell on value (learn this, do this, get better at this, fix this, eliminate this and you will earn more/spend less/get a better job/waste less time) than emotion (find out what happens next!). That's why you won't terribly mind paying $100 for a compiler textbook, but definitely wouldn't pay $100 for the novel from your favorite author. (Unless possibly it was signed, or charity.) Sascha's ebook isn't a story, it's a standalone tutorial. There's no burning need to find out What Happens Next. Meanwhile, when you sell software or educational ebooks cheaply, what you do is attract cheap customers. And pretty much the universal experience of folks selling things to cheap customers is that the cheap customers are more annoying, more demanding, less likely to actually make use of what you sell them (and ergo less likely to buy again), plus price sensitive.
