Recently some things have changed at my office that has left me filling even more roles in our business than I was previously. To put it mildly, I'm spread out all over the place and I need to get organized.

What I'm looking for is some sort of program that will do all of the following:

1. Allow me to schedule appointments.



2. Allow me to view a calendar of my appointments.



3. Allow me to create a to do list and then mark things off that I've done.



4. Email me reminders on due to do list items and appointments.

I don't really care if its a web-based on pc-based solution, just so long as I don't have to have my computer on all the time to send me the reminders. And reminders are the biggest thing I'm looking for here. I'm also looking for something fairly inexpensive as I'll be paying for this out of my pocket.

Anybody got any suggestions?
