I found this yesterday while doing some searching...
Very helpful if you don't want to spend the money on Smartphone notes...
Notebarn
It basically piggybacks off of the tasks/todo list in Outlook, but does the dirty work for you, so you don't have to keep looking through different to do's manually to find your notes....
I downloaded, but did not instasll yet. It looks like it has some good reviews, based on the user opinions I have read.
