The good: Compact and light; frees your media card so that you can shoot more photos; turns your iPod into an in-the-field storage and viewing device; doesn't need a battery; works in harmony with iPod software.
The bad: Sluggish transfers; no automatic synchronization with iPhoto; transfer process can affect battery life; not (yet) compatible with USB media card readers.
The bottom line: Make sure your camera is supported before you add this useful accessory to your iPod Photo arsenal.
