My other problem with Apple is the lack of PDFs. Apple has a bookstore, I should be able to download the whole of Apple's Developer Documentation on my iPad. I would prefer PDF because I cannot read a screen for hours. Plus, the examples are almost always broken and don't compile. Broken samples and videos are horrible ways to teach anything.
