I think when Jobs left, they lost their number 1 innovator.
That doesn't mean the company will sink, I just can't see them going and making products that "wow" us for a while.
For the people knocking iOS 6. What were you expecting? Apple to change their entire UI that every mobile phone users knows how to use, and with ease? They are never going to do that. They're not Android, they don't have to change the look and feel of the software at every ****ing release. Fragmentation at Apple is pretty much non-existent. If you're still using a 3x model device, you need to upgrade, or you need to stop whining about no more updates.
Apple is very much alive and very strong, and will continue to do what they do for a long time yet.
Disclaimer: I loved my iPhone 4. I love Android. I've just ordered a Lumia 920. I am no fanboy.
