SendStation Systems today began shipping its PocketDock AV, a compact thumb-sized iPod adapter providing connections for USB, line out audio, and composite as well as S-Video. The device allows users to sync, charge, and attach an iPod to a home stereo system. The PocketDock AV includes a 4-in-1 cable for USB and AV connections to reduce cable clutter, and comes in black with a design that works with most iPod cases. The PocketDock AV is priced at $40, and works with any dockable iPod model -- including the current-generation video iPod and iPod nano players.
