BusyDo does sync todos from MobileMe, unlike Apples default Calendar, but otherwise has extremely limited functionality. Unless I missed something, the only features it adds are repeating to dos and tags. Unfortunately, because I already happily use BusyCal, which has a multitude of features not offered in iCal, I trusted that BusyDo would be as useful and worth its high price. It is not. Ive tried many to do apps looking for the right one for me—toodledo, 2do, instado, etc. Based on quality, this may be the worst one Ive tried. It is definitely the worst value. Buy something else.
