Getting Organized

Hi all,
I am a business owner who is always working on multiple projects, gets lots of important emails, always has multiple to-do lists, and generally has a number of important ideas floating around at any given time.

I have been looking for a way in which I can get organized but not spend the majority of each day keeping the organizational system going. I guess what I mean is do you have any recommendations for a simple (preferably software based) organizational system which is scalable but can integrate into a relatively fast paced lifestyle?

I would like to commit to one and really stick with it for at least a few months to see if it helps. I basically need to organize my notes, schedule, and to-dos.

Some options I have in mind:
- Outlook (I am a windows user)
- voo2do.com
- Tao Notes
- My Life Organized

Sorry I am giving you so little to work with, but I have only recently taken a serious look at this and would really appreciate some feedback about your experiences and what has worked for you...
