incremental updates do not create stock value in a over saturated mobile market
nor does a do nothing head of retail
nor does an over hyped stupid wearable no one "needs"
(people need phones they don't need a watch)
nor does an iMac with the speed and power of a mobile device
AAPL target = $84
Every industry makes incremental updates year after year. The only reason smart phones evolved so fast is that they were new. At this point a smart phone has reached a near-maximum of features considering these limitations: size, price, battery life.
Also, most electronics feature incremental updates, and their companies do just fine: TVs, cameras, refrigerators, cars. Video game consoles don't change year after year, the Xbox releases were 2001, 2005, and 2013; Playstation releases were 1994, 2000, 2006, and 2013; Nintendo releases were 1985, 1991, 1996, 2001, 2006, and 2012.
And the mobile market isn't over-saturated. Even if everyone has a smart phone, most people replace theirs every 2-3 years. There is plenty of market there, as well as emerging markets in Brazil, India, and China, among others.
As for the do-nothing retail head, she's only been in the job for two months. You should wait at least three months before you call for her resignation.
You complain about wearable tech that no one needs, but you also complain that Apple isn't innovating. Which is it? You can't have it both ways. And when it comes to what people need or don't need, people don't need smart phones, let along cell phones. People don't just buy what they need. They buy what they want and the market will determine what they want. Steve Jobs didn't look at the world and ask what it wanted. He looked in the mirror and asked what he wanted. And it mostly worked well.
And the low-power iMac? It's a desktop with the power of a Macbook Air, which is sufficient for a lot of people. It's a desktop that's priced for people who just need a good computer, without having to spend the money on a higher-end machine. There's nothing wrong with offering products with various price points and specifications. You can still buy the other iMacs.
