Do E-Books Make It Harder to Remember What You Just Read?

Digital books are lighter and more convenient to tote around than paper books, but there may be advantages to old technology.  From @time

I received a Kindle for my birthday, and enjoying “light reading,” in addition to the dense science I read for work, I immediately loaded it with mysteries by my favorite authors. But I soon found that I had difficulty recalling the names of characters from chapter to chapter. At first, I attributed the lapses to a scary reality of getting older — but then I discovered that I didn’t have this problem when I read paperbacks.
When I discussed my quirky recall with friends and colleagues, I found out I wasn’t the only one who suffered from “e-book moments.” Online, I discovered that Google’s Larry Page himself had concerns about research showing that on-screen reading is measurably slower than reading on paper.
