A very insightful piece in light of the recent “controversy” regarding the design of iOS 7.
[W]ith major user interface changes such as Aqua or iOS 7, Apple has another tendency: they overshoot the mark. Their incremental approach then becomes one where unnecessary items are removed (such as Aqua’s stripes) or improved (excessive shadows and transparency are toned down.)
There’s a good reason for this: it’s much easier to take away elements from a design than it is to add them. Simplicity is achieved by removing that which is not really needed.
