I use Evernote for research. I go out and using any device (wonderful!) I capture documents, images, you name it. I put them all in one notebook. Then I parse the documents by re-reading them and highlighting key passages for consolidation in my findings document (also created in Evernote). Highlight is really critical for this. PLEASE ADD HIGHLIGHTING Check out branchfire.com. Their whole app is based on marking up documents. Clearly there is some value to it. Currently, I use text color as best I can.
