Actually for professional photography, multitouch will make tasks such as sorting, retouching, resizing photos a snap. It'll eventually be here. We are closer now, since Apple is cranking up the capacity to make more multi touch screens for iPhone and iPod touch.
Can't wait. Hopefully sooner than later.
