During its WWDC keynote today, Apple announced that its bringing a new MacBook Air to consumers today.

The new MacBook Air boasts what Apple calls an all-day battery life. The 11-inch MacBook Pro will now have a 9-hour battery life. The 13-inch model will get a 12-hour battery life.

The MacBook Air is able to get this better battery life thanks to the new Intel Haswell CPUs. Apple says that it has worked closely with Intel to make the new MacBook Air more powerful while making sure that the battery life is increased. For example, you can now watch up to 10 hours of movies on iTunes with a single battery charge.

In other news, the MacBook Airs now come with the new 802.11 ac WiFi frequency. This is three-times faster than the current WiFi standard. To take advantage of the new frequency, Apple is also releasing a new AirPort device called AirPort Extreme. The AirPort Extreme can be equipped with 1 or 2TB hard drives.

With all these improvements, the MacBook Air has surprisingly become cheaper. The 11-inch MacBook Air with a 128GB HDD will retail for $999. The 13-inch MacBook Air with a 128GB will go for $1099. Both new models will start to ship today.
