I recently purchased a mechanical keyboard with Cherry MX Red Switches, and I find out that it fatigues me more than my laptop chiclet keyboard because it takes more energy to press the mechanical keys than the chiclet keys. That's not to say the keys on the mechanical keyboard are in fact easier to press, but the distance it takes to activate the key is far more than the distance it takes for a chiclet key to activate (even if you only need to press the mechanical key less than halfway down, it's still more than double the distance than it takes for a chiclet key), so a mechanical keyboard for me is slower than the laptop keyboard. And it also takes more energy to suddenly stop my finger's momentum in mid-air with the mechanical key (if I don't bottom out) and manually raise my finger back up than the energy it takes to hit the chiclet key, bottom out, and bounce back with little effort. So I personally feel that my mechanical keyboard is worse than my laptop keyboard.
