I honestly do not understand, or agree with all this sense of a 'failing Apple'. What I hear are a lot of people saying these things, and many believing them, but it's all under a false pretence in my humble opinion.
Apple's products are still industry-defining. I am as excited about Apple as I ever have been. And as an Australian, who's far removed from the United States, and California, I absolutely love the new Ads. I don't expect Apple to come out with some witty, funny, or colourful advertisement every time. It's nice to see this style of advertising from them for a change.
"Hi-DPI" displays in notebooks just last year that have already kicked the competitors into gear. A new Mac Pro that is nothing like any desktop before it, not even the Cube, if you really look at the way the components are integrated. The Macbook Air that still runs rings around the competition when considering its combination of Battery life and industrial design and construction qualities. An all-in-one iMac with a GPU only available on Macs, the GTX680MX and the evolutionary "Fusion Drive". The power saving enhancements in OSX "Mavericks". All these things in my opinion are why I personally feel Apple is as strong as ever, and I haven't even mentioned products or software outside of their Mac division.
A different interpretation of many peoples' impressions of Apple that I have, is that they take Apple's activities for granted. It is human nature and literally part of our physiology to become numb to a repeating stimuli. You will slowly 'switch-off' to a loud droning noise. You will begin to ignore a bright exit sign in a cinema. You will stop being overjoyed every time you win the lottery if you win fifty times in a row. You will, over time, become less excited about Christmas. You will over time, become less overjoyed when Apple releases something great.
All of these situations ring true unless the stimuli is increased; Unless the the lottery win is an exponentially greater sum of money; Unless the noise is double the volume; or the exit sign grows three times the size; or, of course, unless Apple's announcements and releases aren't exponentially more groundbreaking and revolutionary. You could say that the same notion applies to Public Corporations and their need to not only generate a profit return each year, but increase that profit margin. Anything but an increase in profit margin is seen as a loss of sorts, which to me is bordering on the insane, when I look at it from a distance.
With that notion in mind, I feel it is exactly what's happening with regards Apple and their current public perception. People's expectations are exponentially greater each time Apple has announcements to make. It's unfair for Apple, but completely natural for people to feel this way.
Just my thoughts.
