No it isn't. Neither market has been overtaken by commodity products at all. Your argument about Apple products being commoditized is totally without merit. The Mac and iPhone continue to gain share in markets that have commodity alternatives. The iPad sales have slowed but they haven't slowed as much as the commodity alternatives. iPod sales have slowed not because people are buying commodity MP3 players instead, but because people are no longer buying standalone MP3 players.

The tablet market and more importantly its poster boy the iPad (the notebook killer lol) have been swallowed by two beasts simultaneously, from the bottom up, larger size smartphones, and from the top down, hybrid notebooks like the Surface/Yoga that integrated the touch based interface and generally speaking more capable devices not toys.

The MP3 player market and iPods in particular have been swallowed and cannibalized to Apple's discontent by their smartphones and their peers again.

So, it doesn't look rosy for Apple as it's becoming more and more a one trick pony with one single dominant product while the rest are suffering or in steadfast decline and when you take into account that the saturation point for smartphones is approaching, you'll realize that they will need to bring up REALLY something new or face the fate every tech company finds itself sailing the ship through the stagnation storm just to get alive.

I agree that larger smartphones attract buyers who otherwise might have bought a tablet, but there is zero evidence that hybrid notebooks have affected the iPad.

There isn't even evidence that the overall trend foe the iPad is lower growth - just that the upgrade cycle is slower.

As for a 'one-trick pony', that statement is certainly false, as Apple has multiple growing product lines.

Also, saturation for smartphones may be approaching in a few markets, but saturation for the iPhone is much much further off, so your prophecy of decline is empty as yet.
