There are some good reasons that NASA has avoided touchscreens, besides the ones pointed out here:
* Things tend to get loose in microgravity. You don't really want things floating into a touchscreen and performing unintended actions.
* During ascent and descent, it's incredibly hard (potentially impossible) to hold your hands out in front of you to operate something like that. The Orion has hand controllers next to each seat, which are notably lacking here.
