The New Mac Air Book

A truly mobile device needs to be light, thin, and strong enough to take with you wherever you go. It also needs to perform quickly, spring to life instantly, and have enough battery power to keep up with you. It should have no spinning hard drive, no optical drive, and no unnecessary parts. All of that is true of iPad. And now, it’s true of Apple’s most mobile notebook ever: MacBook Air.
Flash memory
MacBook Air continues its legacy of firsts with something entirely new for any Mac: flash storage. Standard. In fact, the new MacBook Air is designed completely around flash storage. But in a totally different way. Typically, flash storage is housed in a package that’s the same size as a conventional hard drive. Yet the flash chips themselves occupy a very small portion of that housing. Getting rid of the hard drive enclosure and using only the parts that matter — the actual flash chips — frees up about 90 percent more space. And just like that, there’s room for other important things, like a bigger battery. Now you have a notebook that weighs practically nothing and runs for hours on a single charge. That’s mobility mastered.
