Via CNet, I received $10 to use on Kindle books. I immediately realized that I could use a copy of Sheila Fitzpatrick’s Russian Revolution 
in order to brush up a bit before teaching the event this semester. I’ve really enjoyed using the iPad to read and take notes on PDFs, but what had always held me back from turning to longer e-books for research was the difficulty in getting notes off the book and into Evernote, which I recently started using after getting fed up with the cumbersome note taking tools native to Zotero (still my preferred citation manager, however). I still wish there was a way to simply capture the notes and send them directly to Evernote without leaving the iPad, but I did find this solution which is much more elegant than I expected would be possible.
