In practical terms, my guess is that focusing will: - occur noticeably faster (for potentially faster shots) - use less power (for longer battery life) -- The fast/re-engineered focusing might then enable you to take photos in new modes, e.g: in an "idiot proof" spray, quickly snapping shots at different focus depths very quickly - which you can select from afterwords. I don't personally see much appeal of the 'idiot proof' application yet, (though I could be convinced) but the first two seem like decent improvements.
