I've already spent way too much time on this, so i thought I'd come here and hopefully get a good recommendation. This is what I'm looking for:
1. calendar with a to-do list/task organizer integrated into the calendar (i.e. I don't want one master to-do list--I want to be able to open up a day in the calendar and add to-do items directly to that date, and I don't want to have to use an "all day" event to do that)
2. unfinished to-do items get pushed to the next day/ability to move to-do items to any other day
3. ability to sync online so I can access and update it from anywhere (somehow doing this through dropbox would be fine)
That's it--I don't care about, nor really want, other bells and whistles. I'm willing to pay a little, but for what I want I don't think more than $5 is really worth it.
