Avoiding carpal tunnel / repetitive stress injuries
delackner: Exercise.You will probably ignore that, so let me say it differently.Every day, at least 15 minutes, cycle, run, I don't care.  Move.Every week at least once, do something (I like Climbing) that gets your whole body, but especially your ARMS dead tired.You don't need any kind of special keyboard layout, just something with good key response.  It is far more important what you are doing with your body when you aren't sitting.
