YES! Evernote: please do some usability testing with checklists on the iPhone & iPad. I just revived a faded interest in Evernote specifically in order to keep a common to-do list between pc, ipad & iphone. But I found on my first attempt that checking boxes on the iphone is basically impossible, and attempting to re-order the list on the ipad was too frustrating to be worthwhile. I will definitely drop Evernote and use different software if I can find something better.
