The MacBook Air is a beautiful machine, but with a puny hard drive, no optical drive and one USB port, sometimes its paucity of ports and specs can put the pinch on you.
The Apricorn Aegis NetDock aims to help you supplement your MacBook Air’s specs by umbilicaling your USB port to an attractive little box that merges four USB ports (two of them powered), a dual-layer DVD burner and a 500GB hard drive (or, if you prefer, an empty 2.5-inch SATA hard drive enclosure).
It’s pretty tiny, too. The Apricon Aegis NetDock is only 6.25 x 5.75 x 2.125 inches. The only real problem is it requires a power cord, but powering all of this off of a single USB port is a bit much.
The Aegis Netdock costs $189, or just $89 if you supply your own hard drive.
