Instead of going out and buying post-its or note pads, I just get a page-a-day calender every year and use the back of the previous day's page. If I do need to post-it, a little piece of tape works wonders.

I use my yahoo calendar for appointments, birthday reminders, etc. My to do list is on my computer desktop using the sticky note icon on Windows 7. In case I don't login to my computer on a particular day I have reminders set up on my cell phone.
