All the pilots I fly with and show them the device love it. They wish the company would furnish them to us so we could go electronic with our manuals etc. Of course as soon as something has to be FAA approved it will cost 100 times more and take 10 years. So for now I lug it around as a back up to what is required in paper format. The dual book format really shines when you are viewing approach plates, for example, on the eink screen and the TOC on the other side for quick access. My wish list is thinner, faster, better battery life. The last software update was a huge help however. Sadly I have been working way to much to be active on the forums. My flight home, not working, is 3 hours delayed so I am killing time. Boy I hate flying!
