Not an MS fanboy at all but I have to say Microsoft OneNote is actually quite good I used to use it all the time to take notes on my laptop. Now I've gotten into the sort of stupid habit of just having a giant text file for each CS class I take that I edit using gedit on ubuntu. It's really sort of stupid but it's made me pretty damn good at doing on the fly ASCII art... When I did use OneNote though it was extremely organized and easy to use. I love how you can have different tabs and stuff for classes / topics. You can go really nuts with the organization if you want. It also saves the second you type something, and the automatic formatting and fonts it uses are very aesthetically pleasing. Although, I haven't used it in 4 years but I can only assume that if anything it's gotten better.
