Ask HN: Why is Apple's new design referred as flat design?
https://news.ycombinator.com/item?id=5875933Is flat design over hyped?
Apple design still have gradient, layers of transparency and text shadow to show depth. How is it flat? Well it is less skeuomorphism but I don't think that means flat.
I agree Microsoft's metro is flat, no shadow, no gradient and feels everything is on same plane.
