If you're, as I am, one of those folks who appreciates an application dedicated to doing one thing, and doing it well, Event Reminder is for you. I have been using it ever since I got my eMac with OS X about a year and a half ago, and it's been flawless. Had a couple of issues with the 2.0 beta, and those were resolved overnight. This is one of those "free" applications for which I'd be happy to pay a shareware fee.
