anybody using one? I have good ole paper sectionals, low enroute IFR and approach plates in a a pretty leather binder, KLN89B GPS in the panel and a Quadra on the Yoke for terrain/moving map and an android in my pocket for web/email stuff. The more I read about the iPad, the less and less I want it as computer but, is it worth it for just replacing the paper and the Quadra? Kneeboard replacment even? Seems like it's a little too big to me to mount on the yoke and that's where I'd want it.
