Business people, and time travelers, rejoice. If you’ve been disappointed with the battery life of your laptop we’d like to introduce you to the new 2013 MacBook Air, delivering true all-day battery life.

The current MacBook Air models had relatively good battery life with between 5-7 hours, but we know that isn’t always enough when travelling coast to coast or staying up all night watching movies and playing games.

The 11″ MacBook Air model goes from 5 to 9 hours of battery life and the 13″ MacBook Air has a full 12 hours of battery life – that truly delivers all-day computing power for your laptop.

Better yet, the new MacBook Air models are available today. Starting at $999 for the 11″ MacBook Air and $1099 for the 13″ model, both starting with 128 GB of flash storage.
