I just want to say, the 2.99 was an awesome price point - from an incentive to buy stand point. With 5.99 including PSDs it seemed like a no brainer.
I love cheap learning materials like this. It would be sweet if there was a standard e-learning app on the ipad and I could buy the courses through that app for $1.99 where all the courses were tech focused.
Khan Academy is awesome, but I want good materials that could even be things like Adrian Cockrofts cloud tutorials etc..

EDIT:
Ok, I read the doc and here is my review.
1. The overall concept of this is fantastic, and I think the example UI you show is clean, elegant and beautiful.
2. I would have liked to see an initial explaination of a thought process on what to first write down, in pencil, about the elements you would have in the UI. Help me know what you, as an expert, may intrinsically know - or be able to do in your head based on experience.
3. Prior to page 20, your example UI image jumps from place to place, then 20+ (mostly, except page 28) it is in the same place, this allowed me to scroll through the doc and quickly flip back and forth to visually compare steps. It would be better if all UI examples were in the same place.
4. To further item 3; I strongly feel this doc would be far better if it were in landscape format. I am reading this on a screen, and it is a PDF. Portrait wastes a ton of space and makes the overall content scaled smaller as I try to see a single page on my monitor at a time.
If you were to put the doc in landscape with all notations and commentary to the right hand side, ideally using 11x17, as the page size, this would be a hell of a lot more consumable. (It is an e-book first. Dont worry about people who print to 8.5 x 11 as much. (I make a LOT of graphic documents for all my clients, and every one of them is 11x17 because the information density and clarity balance on 11x17 is far more than 8.5x11
5. The fact that you included links to examples and resources throughout the document is fantastic.
Overall, I liked this and it was worth my purchase, but i think the formating could be improved for easier consumption.
Thanks!!
