who didn't see an Apple stock correction coming? I don't know a single apple user who is happy with them at the moment (and most of the people I know are apple users) because of the fast product refreshes, and a general loss of direction of the company as a whole.
What made Apple special was that Steve Jobs had a vision, and knew how to pursue it properly. He did not market apple devices as being devices 'for everyone', he wanted to make it special, simple, and expensive, which is what he did.
Tim Cook is a good business man, in that he knows how to run the logistic side of a company. But he wants to bring apple to the masses, which will force price cuts, which will force more laxed QC, which will kill consumer interest and profits. You cannot run apple like you run any other business. Apple was built up around a certain ideal (one I personally don't care for), and to move away from that is going to bring a lot of corporate and shareholder pain.
Personally I give apple 3 years. They will either learn from their recent mistakes and pull through, or they will become the apple of the '90s who have a small cult following, but are always 2 steps behind, and 2x overpriced.
