Still some issues with IOIO connection, but I have been flying with
it. It's B&W only, some ghost images, maybe slow... but readability
in glider cockpit is so much better than anything else, that I am
sure that this is the future of PNA devices.

Since viewing angle is practically unlimited, kneeboard use should
be possible.
