"The advantages of e-books are clear. E-books are immediate. Sitting at home in Pakistan, I can read an intriguing review of a book, one not yet in stores here, and with the click of a button be reading that book in an instant. E-books are also incorporeal. While traveling, which I do frequently, I can bring along several volumes, weightless and indeed without volume, thereby enabling me to pack only a carry-on bag."
