ask anyone occupational therapist if the apple keyboard is recommended over, say, the kinesis advantage pro. if you aren't using a kinesis or one of its real competitors right now, you are not a "keyboard snob"
the apple keyboard:
- has no discernable key travel
- is not split and contoured
- is too small
its probably the biggest ergonomic nightmare out there. fortunately few people actually use them after buying the computer
But if I can fly on this keyboard (and the ones like it such as the MacBook Air) with no problems for years, why should I worry about the "ergonomic" keyboards?
No proof of anything, but possibly more useful data.
