Academic Note Taking App


I'm looking for a note taking app to use in class. I looked at Notes Plus for the iPad and that's the kind of app I need, but I'm not going to buy an iPad. I'm in the sciences and need to be able to draw graphs as well as type regular text.

I've looked at Note Everything, which doesn't allow you to put in text boxes to easily label things like graph axis.

I also looked into Polaris Office 3.0, but it doesn't allow for drawing - I would have to switch to EverNote, save the graph as an image then import it into Polaris Office 3.0.

I also briefly played with EverNote and Skitch, but they didn't fit the bill either.

Any thoughts?
