I own all three of these keyboards/laptops and I agree completely. The butterfly keys on the pretty little MacBook work well enough, and they do allow the MB to be so small and light that it has replaced my iPad for short trips. The MB is perfect for reading HN at the coffee shop, but the new style keys just don't cut it for extended sessions of typing.

I'm hoping that the new MacBook Pro just announced with the new generation of butterfly keys will be as good as the Retina MBP or the Magic Keyboard; it remains to be seen.
