Even besides the market, I've been less and less impressed with Apple lately. I mean I'm typing this on an Apple product, but when people come to me about purchasing a new MacBook I have to tell them to skip this cycle and hopefully the next cycle will impress. Another example is that I don't feel like "Yes I need to upgrade!" to El Capitan the way I felt with Leopard to Snow Leopard.
So yes, the market shifts and they lose a few billions. That happens with a company their size, but what should be more worrysome is that less and less people around you are getting that "ZOMG APPLE!" feeling.
