Personally I prefer Sandy (iwantsandy.com). It just has more features and a more versatile interface.
iwantsandy went offline permanently as of December 19, 2008. I really like ohdontforget.com. It’s better than most reminder services that I’ve tried and is very simple to use. I also use the desktop version for my Mac.
