I find retaining information in digital books much more difficult. I think the lack of a tactile third dimension when reading eliminates a search index in my memory and it really effects how I parse the book. I tried reading the most recent GoT book in digital form and I just could not keep track of everyone (admittedly it had been several years since I read the previous installment in dead tree form, so I didn't have a current index of all the characters fresh in my memory). I gave up about 1/4 of the way through and just watched the tv show :)
