iOS 7
I watched the key note with my girl friend - she is technical but still very much has a girls perspective and can be taken as a good representation of her friends.<p>She flipping loves this redesign and I'm pretty certain my not techie iPhone/iPad using parents will too - and that, is was really matters to Apple, that 98% of their market will love it and not just the 2% of us who build for their platform.<p>I like most of it, the colours are a bit much for me but in the main it will be refreshing to move on to something new. I have been toying with moving to Android but this redesign is enough to keep me on board - if I'm going to have to learn a new OS I may as well plump for the one most similar to what  I already know
