There is very little about it thats 'better' in terms of use or usability, its pure slappy. For instance the annoying behaviour where the call fails>you unlock the screen later>it starts dialling that number>you quickly stop the call>the phone screen blacks out>you open again and have to reenter code is, is still there.
There is genuinely nothing new apart from the brightness controls you can pull up from the bottom.
The problem is, (And I am genuinely trying not to be a fanbois here) is that the original IOS was just about fine for a phone, this is change because share holders are edgy, not because its doing anything new.
I think the fear in that new guys voice is carrying into the product, apple are screwed.
As long as OSX and the hardware remains I don't care, one thing I have concluded after a few months with a top of the range PC, is I will take OSX annnyyy day.
