With a darker background (so that the folders are visible), iOS7 is actually nice on my iPAD 4. But the reality is that it is basically a nice theme, which on Android could have been implemented and tweaked with a simple launcher.
I am happy it has multitasking, finally!
I am most disappointed that it still has the same primitive keyboard, without the possibility of adding something like the Swiftkey app for Android, which is really light years ahead.
I am absolutely amazed that iRadio does not have Airplay capability. Between the relatively poor selection and no Airplay, iRadio is basically useless to me -- back to MOG. If you want something for free, Pandora definitely has a much better station algorithm, plus it supports Airplay, duh.... Apple is embarrassing itself.
Overall, I am happy with the update, but it is more like catching up, rather than anything innovative or exciting. It will slow the loss of market share, but without some real effort, Apple will be a niche player in mobile within a couple of years.
