for the dramatic rise in RSI's including carpal-tunnel syndrome.
This is why corporations have spent billions on office ergonomics since the early 90s when the impact of poorly designed devices began to become appearent.
The keyboard and mouse have resulted in a growth industry for wrist-braces... and more companies than not continue to deploy this ancient I/O method without any ergonomic study. Monitors are too low or too high, desks are not ideally matched to chairs... There are no wrist pads at the bottom of keyboards.
Come on... tell me another story.
Breaking workers is not going to stop business from adopting a new technology if it delivers net efficiency gains. The benefits in increased productivity of the mouse/keyboard outweigh the payments to people who end up with repetitive stress injuries from using them - so business keeps deploying these solutions (while also trying to develop solutions to mitigate their negative impacts).
The same thing will apply with touch-screen.
