I'm still undecided about upgrading my 6 to a 7, as I think next years model might be a bigger leap forward, but I don't understand all the hate and vitriol toward Apple in general for their lack of innovation.
I don't think Apple has ever been truly innovative, but what they have done incredibly well is take an existing product and make it easier to use and others have followed. I had a Nokia E90 Communicator before my 1st iPhone, and it did everything that did and more, but it wasn't as easy and was much bigger.
Before that, the iPod wasn't the 1st MP3 player, but it was the 1st that was simple to use due to a great interface and the iTunes store. Pretty sure more music is sold on MP3 or via streaming services than is sold on physical disks today. Again, not really innovative, but Apple took the lead and others followed.
Apple continue to do this, often at the frustration of users who aren't quite ready for the change. The removal of the headphone jack is a classic example in the 7. In 2-3 years time no new mobile phones sold will have this jack, just like floppy disk drives are no more and CD/DVD drives are heading the same way.
It used to be a nightmare trying to keep information on devices in sync (anyone remember serial cables and Psion devices) and Apple have made that completely seamless. I think that's the thing I like the most about Apple and where they have been somewhat innovative. Creating an eco-system, where every device works together sharing information and updating through 'the cloud' has made life so much easier. OK, it's not perfect by any means, but it beats having to manually sync devices, and it's getting better with each iOS/OS release.
Apple isn't the great innovator everyone seems to give them credit for, but they do continue to make simple to use products, that work brilliantly together, and their design decisions (love or hate them) lead the way forward for everyone else.
