iPhone application screen

On the iPhone you can move your application icons between screens, and into different places on the screen. I fnd that I often set them off moving by mistake. As a perceiving type, and visual, it doesn't really bother me that I then have to scan the screen to find them.

But I would guess that the structured judging types would find it frustrating.

Or do they have a clear plan for where each icon should be, so that they can re-create their ideal structure?
