Having played around with iOS7 a bit, I can say that I mostly like the new interface. Even the new icons if you ignore the Safari one - something really must have gone wrong there - it feels totally out of place for me.

OTOH, this is the first beta out of probably many (considering how stable thing thing currently is - jokingly I'm telling my colleagues that it's as stable as the average Android phone now), so we might still see some changes there.

Of course, the thing that sold iOS 7 to me is the fact that you can finally place the unused and empty newsstand in a folder :-)
