Hm, it smacks of cheapness or some such...I don't know what 'OK' means in this context though...my instincts say no... I mean, if the gift were a jacket or a piece of jewelry would people would intuitively think it at least strange to wear it around first...also I think anybody who would enjoy a book as a gift would enjoy that new book sensation of cracking it open for the very first time, and why rob them of that
