We use this in my school and it's a bit janky. The two big power cables at the back of the drawers can come unplugged and it's a bear trying to get them plugged back in. Also, the sync-ing cables don't plug snugly into the iPod Touch and can easily come unplugged. It's great for storage, but for power and sync management, it falters.
The cart also needs a "server" (a laptop or such) to serve the iPods. There are is no easy place to plug in your laptop power cable or tuck the cables out of the way.
