They are innovating. You just don't know what innovation is.
Wow.
To read these threads, Apple products are behind (smaller screens, no expandable storage, no configurability), Apple doesn't innovate anymore.
I don't think you understand innovation. In the eyes of the designer and the architect, you strip away everything that isn't necessary and focus on solving the problem at hand. For Apple (and for many users including me), the screen size on the iPhone is perfect. I don't want it larger. I know there are some with big monkey hands that want 6" screens. Great, get Android then.
The iPhone and iPad were designed to not have external storage. Why? Because Apple envisions a future where users won't need to manually manage their files. The operating system would do it for them. Take a look at the idea of iCloud. Flatten the file system and present it in one shot. No folders, just an attribute-based file system. That's innovation, but that's also a big change.
Remember that innovation is not equal to invention either. Many people harp on Apple for not being "first"... but what they do is innovate (iterate on the ease of use and application) of particular inventions.
Apple is notorious for removing things they feel are old technology and taking the ax to those things that make technology harder to use. Floppy drives, optical drives, command lines... but they focus on the few things they feel matter the most to users. Yes they don't sell much with user-replaceable batteries, but their battery tech makes much longer lasting batteries in lighter machines that last a much longer time. It's a good trade off. Engineering is all about trade-offs.
They are also the company that gets some technologies to become common place by making it popular. Examples: UI, the mouse, the trackpad, floppy discs, optical drives, USB, FireWire, Thunderbolt, high-res mobile displays, multi-touch. Note: they did not invent any of them... but they made them popular through applicable ease of use.
Apple's stance on configurability is again rooted in ease-of-use and focusing configurability into apps. My son could operate an iPad at 1 year old. My grandmother can use one too. I've been a systems architect for 15+ years and I still cringe when I have to use Android. It's not polished and has a poor UI/UX. Sure there are some who don't like the lack of configurability, but it also makes customer service a lot easier and learning the device easier as well.
So maybe Apple products are not for you, but it's probably for the 90% other users who appreciate this refinement. Remember, Apple's DNA is to create technology for everyone, not just tech geeks.
