Features of Apple’s MacBook Air
The two MacBook Air models, 11-inch and 13-inch, are ultraportable laptops, ideal for students and road warriors and light-weight alternative to Windows alternatives. Apple has stripped out components that aren’t generally needed on the road in an effort to keep size and weight to a minimum.
The Air employs solid-state flash memory (64GB, 128GB, or 256GB) for mass storage instead of a hard drive, reducing size, weight, and power consumption while allowing an Air to wake from sleep almost instantly. Other MacBook Air features include
