Matt Gemmell's astute take on the design of iOS 7:
“iOS 7 is much, much lighter – in the colour sense, and consequently also in visual weight. Breathable whitespace is everywhere, and is used to unify and homogenise previously disparate interface styles.
The overall impression is of brightness and openness. The extent of the change (and its consistency of application) only becomes obvious when considered in aggregate.”
This is true, there is a certain lightness to iOS 7 that seems refreshing. Call me crazy, but I expect that in the coming years we'll all be describing Apple software this way, using terms like: refreshing, room to breathe, airy, clarity, calmness, fluid, and so on.
Seems pretty Zen, doesn't it?
