Many times we get some or the other attractive article, image, or document as an attachment in Mail. There are many possibilities to save them, but if you wish to view them in offline mode, saving mail attachment to iBooks is the best possibility. Of course, you can use iCloud to save mail attachment as well.
The only drawback to saving an attachment in iCloud is that you'll need internet access to view the attachment. But if you have saved it in iBooks, you can view it offline.
