I'm sure the display technology will continue to improve
dramatically. I am most frustrated by the (lack of) input options on
touch-screens. My Oudie and Android platforms are almost useless in
temperature extremes (below freezing or above 100F), do not respond to
touch inputs reliably, even though I can read the screens easily. The
challenge is to find a platform with a decent display, configurable
mechanical inputs, and soaring software to take advantage of them,
without breaking the bank. I'm not sure that's the direction
commercially-driven development is going.
