My son, a radiologist, called me yesterday all excited because he had just downloaded a two volume several thousand page comprehensive CT and MRI radiology reference manual to his iPad. He is so pleased that he can search the text, insert bookmarks, and highlight passages and it weighs almost nothing to carry around compared to the printed version's several pounds per volume. It is much faster and easier to use on the iPad. He does have one complaint, the electronic version costs as much as the printed version.
