Am I right in thinking that this would lead to the same
problem of tap-to-click touchpads? I mean, tablets and PDA
are mobile, so they are susceptible to impact. This leads to
actions being invoked when you don't want them (see Kelsey's
remark).
The trigger mechanism of keyboards and mouses (mice) sort of
prevents this. As for PDA's, touchscreens tend to have
actions disabled unless unfolded or switched on. In fact,
there is even software to even disable to effect of many
buttons, which tend to get pressed in one's pocket (not
deliberately).
Best wishes,
Roy
