I thought this was pretty interesting. The basic problem of lack of tactile feedback is one you can test easily by trying to type on on an iphone vs. an old school blackberry while riding a roller coaster. When you have something to brace against, it's just a lot easier to be stable. I'm surprised researchers haven't figured out a way to solve this in a better way (maybe it's a haptic screen that can be reconfigured... the way LED keyboards work) The 20% error rate the pilot describes seems... like a really really big problem.
