iOS also isn't as good at home screen layout; moving an icon causes others to jump around. Despite visually being a grid, the icons are internally modeled as single line that wraps like text. If you add or remove an icon from a higher row, every icon below it moves, including jumping between rows. I can understand how this mistake was made before the app store, but it's bizarre that it hasn't been corrected.
