I am a huge fan of Evernote. If you have not taken a look at this product you should. I have it loaded on all my devices (IPad, Netbook, MacBook, and Blackberry). It is my main note taking software as well as the product I use to take screen shots on a regular basis.
Unlike Google Docs, all the information contained within Evernote is synchronized locally on each device so you always have a copy of what you need.
