Hand rests are only half the problem--even with a totally steady finger, it's tough to consistently find a small area on a touchscreen (and that's even ignoring the level of customization the F-35 allows) without looking at it. The author wasn't joking when he talked about inputting coordinates without looking at the control panel, and I expect it to take some massive advancements in haptics before we can do anything similar with touchscreens.
