I definitely agree with the Kevjones. It gives nothing except pf the non-working apps.

So what does it give? And for whom? IMHO - troubles.
1) for developers: how to adopt fast the apps to the new screen.
2) for firms - where to request the apps adaptation and how much to pay

Apple made the visual product update + bigger screen - nothing more. No FIPS-140-2, no LTE, a lot of restrictions (e.g. iOS 5-6 do not support the Zebra printers http://www.zebra.com/gb/en.html and hundreds of other hardware). This list can be quite long....
