Reading the latest MacWorld, I noticed a trend there that I’ve seen elsewhere: the use of iTunes to transfer .pdfs to iBooks. While this certainly works, it seems terribly inefficient, especially with a more viable option. I email .pdfs to myself (especially with the Mail PDF function in Apple’s print window) and then open the attachments on the iPad. Once the attachment is open (in a new tab in iOS 5), two buttons appear at the upper right, one that defaults to ‘Open in iBooks’ and the other that allows opening it in another reader or app. (If these buttons disappear, which they will after a few seconds, single tap the screen and they will reappear.) That ‘Open in iBooks’ will allow seamless (and wireless) transfer to iBooks.
