I switched one of my AOL accounts over to Outlook several months ago because I finally able to get a hold of copy of that program that actually worked!
I love using it because of the Calendar feature and the tasks feature. I like having everything outlined for me at my fingertips.
It's also very helpful for businesses. I run an amateur fan magazine for Lord of the Rings, so it helps me keep track of orders, payments, submissions etc.
My advice is use it if you really feel it will help you. You don't neccesary need to run a business in order to benefit from it.
