As in paper?
Also, inflight wifi might not work, back to papers.
I find it scary that a first gen/second gen device are considered for situations where lives could depend on it. Better let it mature for a few years. No need to rush this. I fly about once to twice a week continentally and at least once every two weeks up and down from Europe to Asia and I'd like my pilots to use trusted methods.
Again, I don't mind that they will eventually move to HARDENED systems for this. But consumer grade hardware, no matter how "magical" it might appear to the fanboy base, should not be used in cockpits just yet.
