The Iliad has a touch screen, but if you are in the US the Kindle may better fit your needs. It does not have a touch screen, but it has an innovative "select wheel" that allows navigation vertically in the page and a keyboard for entering notes.
The other thing that is unique to the Kindle is that it can search everything on the device at once. This includes your notes and "clippings" (which could be quotes - however some ebooks don't allow clippings).
