Accessory maker Apricorn is now offering a Mac Edition of the Aegis NetDock, originally designed to add functionality to netbooks. The device, about the size of a standard external hard drive enclosure, combines an (optional) 1TB drive, a four-port USB 2 hub, and a dual-layer DVD burner. The design allows for the hard drive component to be swapped out if users desire larger capacities, and the drive is compatible with Time Machine.
