Hi Andrei, Lilly, et al.,
Couldn't let this post (below) go by without pointing to the "pilot error" analogy. When a design is just good enough that it is *possible* for the pilot to have taken the correct action (however unlikely in the actual context of use), when the design fails the pilot, the official cause of the failure is "pilot error."
Yes, if users were better-informed, more self-motivated to avoid RSI, altered their behavior accordingly, had wider carpal tunnels, bought the most ergonomically advantageous input devices, they would succumb to fewer RSI's.
