I think there is a market for a large, physically demanding computer keyboard. The keyboard 'keys' would require pressure from a full hand to activate, and the return and backspace keys could have a different type of lever action (pull to the side maybe). The operator would have to stand, which seems like a trend these days, and the PRO-version could come with a large inverted water bottle. Not joking about the keyboard, only half-joking about the bottle.
