Variants of Apple's MacBook Air got cheaper in Australia overnight as Apple reduced pricing and at the same time boosted the spec.

The lowest price point remains $1099 for the 11-inch MacBook Air with a 128GB solid state drive (SSD), but it now comes with a faster 1.4GHz Intel Core i5-4260U CPU compared to the previous version which had a 1.3GHz Core i5-4250U CPU. You still get 4GB of RAM.

What's the difference between an Intel Core i3, i5, and i7?

The pricing has changed on all the other models has dropped by $50. The 11-inch MacBook Air with a 256GB SSD now costs $1299 (from $1349), and it, too, gets the faster processor.

The larger 13-inch model has the same updated CPU and is available for $1199 for the model with the 128GB SSD (down from $1249), and the model with the 256GB SSD is now $1399 (down from $1449).

Battery life is said to have received a boost due to the new processor, with Apple now claiming up to nine hours of iTunes movie playback for the 11-inch MacBook Air (up from eight hours), while the 13-inch MacBook Air now gets 12 hours of iTunes movie playback (up from 10 hours). The other quoted battery life values remain the same (nine hours and 12 hours of 'wireless web' for the 11-inch and 13-inch, respectively).
