Apple deserves credit for improving the MacBook's battery life and disk speeds, but other than that, this is, for better and worse, the same machine as last year's model. If you previously shied away from the 12-inch MacBook because of the "one port" thing, this still isn't the laptop for you. But if portability and screen quality are a priority above else, you can take comfort in knowing that this year's version is just as good in that respect, and that the performance is materially better.
