By not being able to lock the damn icons in place on my iPad. I know it sounds trivial, but my three toddlers love to use the pad and it keeps them occupied for hours, but the little 'darlings' always drag my icons around, mash them up into floders where I can't find them, empty the dock and generally trash the UI. Tonight I get in from work and it's the worse yet, so I lose my rag and ban them all from going on the pad for a day. My wife thinks I'm some bad tempered ogre who can't/won't share my rattle etc. So quite simply, why the hell did apple remove the icon lock in the dim distant OS and is there actually a way to lock the icons/folders through an app./trick? Oh and a toddler 'drool' proof screen covering that worked would be useful as well. Mr being driven slowly insane..
