I chose both PaperDesk and PenUltimate. I've settle on PaperDesk - which does a find job taking notes. It also allows me to highlight parts of the note, circle important thoughts, etc. At first I thought that the method for handling the notes was a bit cheesy - you clicked a button and the note is pasted into an e-mail and added as an enclosure. But I actually found this pretty cool - since when I got back to my main computer I could save as, print, etc. I also created a gmail folder to store all of my PaperDesk notes. What is also cool is that I can take notes and then e-mail them to people who need them.
