This is more complicated than the article implies. While it is true that Google and its partners have done well to corner the low and medium ends of the market, they have also produced phones which many objective users (e.g., those not unusually invested in Apple products) considered on par or superior to the iPhone (the Samsung Galaxy SIII being the premiere example but also the range of Motorola Razrs and even my good old Samsung Galaxy Nexus). Moreover, recent iterations of the iPhone have had serious issues in terms of design and manufacture (for a non-scientific anecdotal evidence, my wife's iPhone 4S has had numerous problems with the volume rocker and poor call quality, and an associate has given up on the iPhone 5 after having 3 replaced due to the battery overheating).
Apple produced a true innovation with the introduction of the iPhone, and they deserve commendation for this and their focus on design and usability. However, their products are not flawless, their business plan continues to rely on charging a massive markup, and their insistence on a closed ecosystem prevents innovation and even attempts bizarre forms of social manipulation and anti-competitive practices (see the story today about Apple pulling the 500px app for making it too easy to find nude pictures, or the difficulty getting a program that competes with Apple software into the ecosystem in a non-hobbled fashion).
Now people are free to pay extra for a device to capture social capital, and Apple is free to take advantage of that, I would argue, however, that relying on being stylish to eek out massive profit margins is not the best long-term business strategy. Neither is insisting on maintaining a narrow product base, preventing expansion into low and medium end markets. Or how about a larger screen, like the market is asking for?
Apple is a great company, and good to have around to spur the competition. However, as we have seen previously, they are also capable of stumbling from the top tier in relatively quick fashion, and when that happens we get Windows ME.
