3. You could have a limited number available for in library use only for a limited time period.

5. You could have one of the members of your library staff stand in a high traffic area away from your reference desk carrying an ipad and offer to help patrons as they wonder through the stacks.
6. You could load some ebooks on them and check them out since unlike the kindle this is probably allowed. Although you would need to have the patron sign their life away, in order to be able to use one.
7. You could consider having your staff use ipads instead of your regular computers. This may or may not work but if you could make it work, you may be able to say a lot of money.

9. Get rid of all or some of your library computers and replace them with ipads for your patrons to use instead.
