Yeah, you're not the only one who thinks that. The takeaway feeling is that Apple has stopped innovating. Besides the fingerprint reader, nothing really "popped out". A speedier SoC? Not surprising, it's a given with any new release at this point. M7 co-processor? Nothing we haven't seen, Moto-X gave us a glimpse of what co-processors can help with. A focus on camera? Not something we haven't seen, we saw the HTC One and how they proved that bigger sensors equals less noise and better low-light performance.
iOS 7? Eh, I'm still on the fence with it, I personally haven't tried it yet. But the feeling I had back at the WWDC revealing is that it's more "catch-up" rather than "complete redesign".
And not to bag on Apple, because I feel the same way about Android on the software side too. Google's slowed down with the "big releases" (ala jumping from 2.3 to 4.0), and every new release (from 4.1 to 4.2 to 4.3) has been...minimal really. I wouldn't be surprised if 4.4 Kitkat followed the trend of minor refinements.
It's good to see Apple releasing an affordable line of mobiles, that was always one of the biggest complaints from people.
You've misunderstood. It's not "new" per se. The iPhone 5C shares the same guts as the iPhone 5. Just in a different outfit. So it's not new. Affordable? A lot of people (who are clued up) say otherwise, since it's basically last years phone (in plastic, rather than metal no less), and you can get the 5 for more or the less the same price.
The strategy isn't new either. When Apple releases a new iPhone, they always sell last year's model at a lower price. Just that they've dressed it up this year.
