No, but I will tell you one thing.. Apple is stagnant.

They’ve been forced to raise the price of their products in order to make up for the reduction in sales, especially in China where Huawei and Xiaomi are eating their lunch. In the beginning Apple was selling well there because they were portrayed as a ‘luxury’ brand but now Huawei makes phones just as or more (see Mate X) expensive than Apple, Chinese no longer need to buy Apple when they can buy a Chinese product and support their own country.

Like all the other answers said, Apple’s financials are still great and they are still taking the lion’s share of smartphone profits – no surprise there. But they are in danger of losing their market share, and they cannot keep raising prices of their products in order to make up for it forever.

And one can easily see why they are losing market share – they are a premium product. The cheapest macOS device is $799 (Mac Mini). That’s insane. that was $499 a few years ago, and the price increased 60%. The new Macbook Air Retina starts at $1199 – a 20% increase from the old $999 Macbook Air. They are pricing themselves out to the point where only Apple faithful will keep buying.

They are basically coasting on their high loyalty customers – but who knows how long that will last? Apple Watch, AirPods, HomePod, Apple TV – what do all these have in common? They are for iOS / macOS users. A Windows / Android user has no incentive to switch over. If they are not on iOS or macOS the products Apple sells are not going to work well – or not work at all.

Another symptom of decline is instead of focusing on new R&D they’ve been iterating a lot on existing products. Look at how many iPads they sell now – the low end iPad iPad, the smaller iPad Mini, the more premium iPad Air, the 11 inch iPad Pro and the 13 inch iPad Pro

Now let’s look at the iPhones they are still selling – the iPhone 7 (for some reason still selling on their website), the iPhone 8, the iPhone XR, iPhone XS and iPhone XS Max

Now lets look at the Macbooks – there’s the 12 inch Macbook, the old 13 inch Macbook Air they are still selling, the 13 inch Macbook Air Retina, the 13 inch Macbook Pro without touchbar, the 13 inch Macbook Pro with touchbar, the 15 inch Macbook Pro with touchbar

Wow, that’s a lot of overlap.

Remember when Steve Jobs came back as CEO and focused Apple into making only one product for each category? Consumer desktops, consumer laptops, professional desktops, professional laptops? Apple should really take note because confusing consumers is not really what Apple stands for.

Steve Jobs made it easy for non Apple users to get into the ecosystem. Buy an iPod Mini, release iTunes for Windows, switch Macbooks from PowerPC to Intel architecture etc these are all moves done to make Apple more mainstream. Tim Cook has done the opposite – all his new products are only for use by existing Apple users. If I wanted to just get an Apple Watch but I have a Samsung phone – uhh nope doesn’t work. HomePod? doesnt work with Spotify or Tidal. AirPods? Yeah they can do bluetooth – but you lose out on that special W1 chip and then there’s no reason to get it over competing wireless earbuds.

And even to Apple faithful – how many customers did they lose with that Macbook Pro all USBC move? the butterfly keyboard? taking away the headphone jack in the iPhone 7?

So while Apple is far from being dead in 2019 they are certainly on the decline.
