Mac Observer points out that a quick exploration of iBooks reveals full, official manuals for your Apple hardware that you never got in the box.
Just open the iBooks Store and search for Apple Inc. Several programming guides are available too.
These days most of us have enough experience using Apple products and other other computers, phones and tablets that a lot of what’s in those guides isn’t necessary, anyway. And by not including documentation, Apple helps reinforce the idea its products are so intuitive to use that you just don’t need documentation.
That’s not to say that Apple doesn’t produce really gorgeous, helpful, complete documentation for its products. It just doesn’t print it and stick it in the box. Fortunately, there’s a solution, and it’s built right in to every iPhone, iPad and Mac.
