Why do so many keyboards still raise the back? I thought this is exactly wrong ergonomically because it forces your wrists to bend up. They should raise the front of the keyboard so it slopes downwards and leaves your wrists in a more natural position.
Bend your fingers. Now straighten them. See how your fingertips trace out a curve? That's what the sloped keyboard is for. Your wrists should never bend up. If they do, either your chair is too low, or you're trying to put your wrists on the desk and type at the same time!
