It's true, Apple's track record is phenomenal, there were no real touch-screen phones, no tablets, no app stores, no online music stores of any consequence, until Apple invented them. And, of course, you can go back further to the personal computer, GUI operating systems etc. etc. Phenomenal. And then what we see is all of the "me too's" simply creating variations of Apple's products. There's little expectation on Samsung to come up with something new (and even less for Microsoft), these other companies are not expected to innovate, and yet somehow people expect Apple to keep inventing a new thingamajig that no one has thought of before. It just doesn't happen, at least not that often. For Apple, it's been 4 or 5 unique things that have truly changed the world, for most other companies it never happens, they contend themselves with a "copy or die" strategy that brings in quick dollars, until they can copy the next thing.
There is an incredible spirit of innovation at Apple, and we will see new inventions and amazing products, but to expect this on a 6 month basis is ridiculous. There's very little praise given for refining, improving, making something great even greater, but sometimes little steps are needed before giant leaps can be taken. The negativity shown toward Apple recently is certainly unwarranted, and definitely hypocritical, in the light of the low expectations afforded to other tech companies.
