Holy crap, doesn't any one realize that the high resolution displays don't need shading and dithering to make objects look nicer. That was a necessary evil for low resolution displays to make things look nice and pretty. Tiles and objects on UI's are still the same size, but the resolution has double/tripled/quadrupled in some cases. So we don't need rounded, shaded objects any more. Flat designs look like crap on low resolution displays because we see the jagged edges, so shading was used to soften edges.
