Carlos Gomez might not like what Apple has in mind for the future of the notebook Mac, but he absolutely nails the approach it's taking:
When Apple finds an opportunity to rethink a popular device, they engineer it to the user and use cases three years down the road and wait for the hardware and software to catch up. They’re rarely content in just making a better version of what they already sell. That’s a recipe for being leapfrogged in the marketplace by a younger and less-entrenched company. It’s a story they wrote. I think it’s not too risky to say Apple lives in a perpetual fear of having what they did to Palm and BlackBerry done to them by someone with clear vision and nothing to lose.
