The Origami Workstation (my review) is what I use for using a bluetooth keyboard with my iPad. However, because the side bezel of the iPad Air and the iPad mini are so thin, the bottom part of the screen is difficult to tap when the iPad is set into the Origami.

A cheap “fix” that someone showed me on Twitter is to put a carpenter’s pencil underneath the iPad.

Update: Check out Tyler Hellard’s even better solution that uses the Smart Cover.
