Put the iOS images side by side, shit even ignore the ios7 images, and the difference is gloss(and button shape). My point is that layout/placement of elements seem to be a constant, while it is actual dress that is the differentiator. Functionally it seems that iOS hasn't changed. The lock screen looks different, but seems to behave as it does now (the bokeh effect is the only thing that compares from this article). And I can't fault them for taking WebOS' multitasker, every small-screen os should use it.
