If you enjoy a good old fashioned pen and paper list from time to time, the Paperback iPhone Case makes it easy to jot something down on a sticky note – since you always have your phone close by. Of course, you’ll have to start carrying a pen, too. Paperback’s pages have a removable adhesive on most of their surface, which will keep the note flat against the phone. You can also do a quick scetch or something like that. Cool.
