The MacBook Air features a 1.8-inch hard disk drive with 80GB of storage capacity standard. A 64GB solid-state disk (SSD) drive is an option. The hard drive is a Parallel ATA (PATA) model that operates at 4200 RPM.

Apple's frequently been in the crosshairs of environmental group Greenpeace in recent years. Jobs offered information about the environmental goals behind the MacBook Air -- it has a fully recyclable aluminum case, and is "the first" to have a mercury-free display with arsenic-free glass. All the circuit boards are BFR-free and PVC-free, and the retail packaging uses 56 percent less material than the MacBook packaging.

It's priced starting at $1,799 and will be available within two weeks.
