Resting on their laurels? Not from my seat, in the last year or so:
- A new line of iPads in 2 sizes with the addition of highly regarded stylus. This product has made the biggest change to my working life in the last 5 years (completely ditched paper - all notes now taken digitally).
- New True Tone display - massive difference when using iPad outdoors (hope this tech filters to other iOS devices).
- The A9 and A9X: designed in house, well regarded performance.
- iPhone with 3D Touch - something else which has made working life quicker (can get through dozens of emails in a much smaller amount of time).
- Research Kit: fingers crossed this leads to some good.
- A completely new MacBook line (Retina 2015), introduces several firsts for Apple - USB-C, new Butterfly mechanism keyboard, fanless, custom shaped battery, individual LED backlit keys (as opposed to an array previously), Force Touch trackpad.
- The 2105 MacBook (Retina) has also just received an internal upgrade with some decent performance boosts.
- Expanded Transit directions in Maps to new cities.
- A new Apple TV with a much requested App Store.
- Roll-out of Apple Pay to new countries.
- Released 2 operating system updates (OS X 10.11, iOS 9) and 2 new Operating systems (watchOS and tvOS).
Like you say the growth was never going to continue forever. I'd sit and watch. If the overall decline continues for a number of years then maybe worry. As a shareholder I'm not worried one bit. The Icahn sale has allowed me to buy more at IMO a good price. The points he Icahn about China are valid - and something to keep an eye on.
Besides, Apple has always been slow. Rarely are they first to market. And even when they do, they release products which to most people are "lacking". It has worked well for a long time:

OLED will come. You can just go to a supplier and ask for 200 million+ of something a year. That's one of the sad parts of success. Some things take longer to procure. Just like Touch ID sensors, very limited at the start and were a bottle neck. Also maybe there were waiting for the technology to mature OLED is fairly new (and has been improving a lot over the last few years). Ive himself has spoken of the benefits of the OLED technology on phones. From the rumours it appears they are lining up something for 2017.
On the other side I don't really see a huge difference between the OLED on my Watch and the LED on the iPhone. Both are good. Tap to wake would be nice. But I'm not going to worry if they stick to LED.
All nice to have but none of them are going to set the world on fire. Without striking new designs to see, Apple's reputation for innovation will inevitably diminish in the eyes of the average consumer.
