New MacBook Airs announced featuring Haswell chips, better battery life and faster wifi

Apple has just announced the new MacBook Air at WWDC 2013. The new MacBook Airs are still available in 11 and 13 inch models but will feature new Haswell chip technology which means better battery life. They'll also boast faster graphics performance and 802.11ac WiFi networking.

While we aren't getting retina MacBook Airs just yet, the new Haswell chips will bring the 11-inch MacBook Air from 5 hours of battery life to 9 hours and the 13-inch model from 7 hours to 12 hours. Both models will also feature an 802.11ac WiFi chipset. The new Haswell chips will also bring with them better graphics performance and about 45% faster overall performance.

The battery life improvements are about the equivalent of watching a full 10 hours of iTunes movie playback on a single battery. That's pretty decent.

The new MacBook Airs are available starting today. The 11-inch model will start at $999 while the 13" will start at $1099. Anyone plan on picking one up?
