Here is a prime example of how slow iOS 7 is on my iPad 3. If I go into settings to change the background screen and chose an image from one of my Photos albums, it takes several seconds to display the image. You can move and scale the image to better fit the screen, so trying to drag the image nothing happens for about 10 seconds, then suddenly the image moves. Ten freaking seconds to drag the image 1/2 inch! I also notice delays of up to 10 seconds when pressing buttons/icons in Photos when trying to select an image to use as the background. So pressing the square box with arrow in lower right of Photos app takes 3 seconds to display the popup control options. Then pressing the Use as Wallpaper button/icon and it takes 10-12 seconds to display the image. I already discussed slow dragging. Pressing the Set Both item takes 3 seconds to return to album. Pressing the Home button can take up to 10 seconds to return to the Home screen, though it often closes the app more quickly.
