Correct. You don't *see* them.
Again, Sales are the very very last indicator. By the time you see the innovation on sale, it's 3-5 years too late to keep up.
There is always another Sony or RIM or Apple. Innovating, genius-driven, off of everyone's radars.
Swipe to scroll is not what changes the world. And Apple's "innovations" now are of that magnitude.
You didn't read the comic.
It's not just rate of sales that matters, but rate of change of that rate. Or even the rate of change of the rate of change.
See what I mean?
Put it another way. You are a fish that is swimming at 50 feet per second away from a shark.
You can self-congratulate over the fact that your distance from the shark is increasing.
Or you can quietly remind yourself that sharks can swim at 100 feet per second.
Hmmm...you are implying that the rate of acceleration relative to past sales is decreasing, correct? The problem with that assertion is that sales numbers don't agree with it, in fact they show the opposite. Both the absolute and relative acceleration in sales of iPhones each year is increasing, not slowing down. As another poster pointed out, don't look at the smartphone market, at the entire mobile phone market, and there is your true measure.
Your other assertion, and correct me if I am wrong, has to do with innovating, and coming up with the next big thing. You then seems to isolate Apple as a Phone company. Apple is a personal electronics company. Comparing them to Nokia and BB is inherently flawed. Apple is not nearly as reliant on the iPhone as Nokia or BB are. They are much more diversified, and a company jam packed with examples of innovative and revolutionary product category creation. The Apple I revolutionised personal computing for the mainstream consumer. The Macintosh did the same. The iPod did the same for portable music players. The iPhone for mobile phones. The iPad for mobile computing. This not to mention several other landmark hardware and software products, like the PowerBook, the Macbook Air, Mac OS, iOS, iTunes, the App Store, being the only company designing its own hardware and software together - resulting in, for example, optimised proprietory mobile silicon that outperforms all same generation devices both in real world performance and raw benchmarks.
I would like for you to name a company that has led the way in innovation in the tech industry as often and in as many categories as Apple has done and continues to do. Name a company that has inspired an equal number of imitation and "me too" products from its competitors such as Windows, Android, Zune, virtually every flagship smartphone since 2008, virtually every mainstream tablet since 2010, the "Ultrabook", the modern all-in-one desktop, etc.
I wouldn't worry about Apple lacking in the innovation department, but I also wouldn't expect them to release a revolutionary new product category every couple of years. I think if you take a step back and look at the iPhone, and take the original up against the 5s, objectively you would be pretty impressed with the advancements made, both on the hardware and software front.
Also would challenge you to name another company as unafraid of canabalizing its own products or making its own hardware or software obsolete for the sake of progress as Apple. Two major software/hardware architecture changes, first to PowerPC then to Intel. Making the iPhone the very best iPod you could buy. Making the iPad good enough to replace a laptop for a large section of the consumer demographic.
Nothing you are saying seems to be connected to any hard data points or have any historically factual basis. It seems as though you are basing your opinion not only on the Apple of the just past 4 years or so, and disregarding everything before that with little knowledge or insight into what Apple may or may not be working on for future products in both the smartphone and other personal electronics categories, but also on generalisations that there is an unknown dark horse that is going to condemn not only Apple, but the rest of the smartphone industry to rapid and irreversible decline.
You are certainly entitled to do that, but you should then expect sweeping statements of doom to be called out and challenged.
