I really like my DR1000S. It's great for reading PDFs and even for regular ebooks as you get a lot more text per page. I've put my Iliad in the closet and just use the DR. Of course I do almost all my reading at home so the large size isn't a huge issue. I also liked my Iliad, but I'm not using it much any more. I also love the fact that they're open and not tied to a specific vendor like the Kindle is.
Just my $0.02
