My favorite thing about the Apple "mighty" mouse is how it's ergonomically designed to absolutely ensure that you will get carpal tunnel syndrome.
@Averly I mean, the trackpad isn't GREAT, either, but at least you can use it with your fingers on it and your hand raised. The mighty mouse you MUST cradle in your hand with your wrist pointed down at an angle.
@SuzanEraslan I'm so used to just resting my hand, using a mouse seems foreign now.
