But with certain things, ergonomics is actually paramount above everything else. The best examples? Keyboard and mice.

Some company can design a keyboard with all kinds of lights and shortcut keys, but if I can't type comfortably and fast on it, none of it matters.

Some company can design a mouse with insane precision and loads of buttons, but if my hand hurts after using it for a long time, it completely fails. This is why the best mice are usually asymetrical, because a person's hand is asymetrical!

This might not matter for casual computer users, but for power users it's an essential quality.
