What type of information are you planning on?
MS has a built in Address Book. I know it's simple and very basic but it's a start. Other than that, each program in themselves store different things, so depending on the information you want, it'll help a-bit.
Ok, this is what I would like. As I am a journalist, I have stored hundreds of infromation like names, phone numbers, addresses, emails, and also I need to have a scheduler, and something to write my notes in.
