if you check email every day, Trumba dot com is fabulous.
I use it the way you use your day planner.
I plug in everything I need to do on what day + time and place I need to be.
In the morning, it sends me an email of everything I need to do today.
All the way down to the phone numbers, addresses, mapquest links, and notes I wrote .
I would die with out it.
well.. not really... because google calendar is looking good for far cheaper then I spend on Trumba.. but you get the idea.
