Apple launches new MacBook Air ultralight laptops

Apple has unveiled two new MacBook Air ultralight laptops that has features from the iPhone and iPad as well.

One has a screen that's 13.3 inches (33.8 centimetres) diagonally. The second has an 11.6-inch (29.4-centimetre) screen. Prices start at USD 999.

Like the past generation, the MacBook Air can't read CDs or DVDs.

This one also doesn't have a hard disk drive. Instead, it uses all flash memory, like the iPhone does.

Apple also announced a new version of its operating system, called Mac OS X Lion that will include a store for Mac software.

It's similar to the iTunes store that sells apps for iPhone, iPod Touch and iPad.

It is adding FaceTime video chatting to Macs. That feature debuted this summer on the iPhone 4.
