Interesting concept video for using iTunes, rather than the iPhone itself, to manage home screen icons and layout. Single icon, multi-icon selection, icon and space lock and unlock, whole screen moving, sort by name, sort by last usage, etc. are all visualized and it makes a rather compelling case.
Would you rather (or additionally) handle icon/app management via iTunes? As we move to more wireless/over-the-air syncing and operations, do we want to have more reasons to stick with the tether, or could a MobileMe-like service include it?
Also, while it looks solid on 2 screen, what if you're rocking 9 screens, will it scale?
