Hopefully it's not too early for a shameless plug.
But, my company has a note-taking program called
NoteScribe, which yes, we did create, but I use it every day for keeping all of my sales and marketing together. It's really convenient if you need something to help keep your school, business, or home notes organized. A lot of our friends are using it in undergrad and grad school, and a lot of business folks have bought it in the last few months. Anyways, give it a try and see what you think.
Again, sorry for the shameless plug so early into my tenure hear!
