I don’t think so. Apple brought out the Iphone and, it took a while, but now there are many phones like Iphones.
In all markets, there has always been a breakout product that nobody can touch, but eventually all the competitors always catches up.
So, assuming that others don’t quit the market, they will eventually catch up.
Especially now that Apple doesn’t have the advantage of Steve Jobs.
The article argues otherwise. Apple's iPod still owns 78% of the music player market. Sure, the iPhone 4S was a disappointment compared screen-wise to the Galaxy Nexus, but Apple will catch up and blow by them on the next iteration.
In the long run, however, the picture may not be so bright: Paul Graham believes Apple is toast without Steve Jobs. It's highly unlikely that Apple will not succumb to the "big company" disease.

The iPhone sucks
Apple is doomed
They should sell the stock and return the money

Like an iPhone, is not an iPhone and the sales prove it.
