iTwinge iPhone Keyboard Video Makes Me Cringe a Little LessS

I'm slow as hell with my iPhone's keyboard, and tend to only check emails, or send quick responses. I should probably just suck it up and get faster, but I'm curious if the $30 gizmo would help. Having to slide the holster on and off between emails (to use the screen again) could be a pain in the ass, though. Overall, a little less skeptical than I was, what about you? [itwinge]
