The actual Dock+ is not much more than a large piece of plastic that has been molded into a single solid chunk. The designers left the bottom open so that they could stuff all the extras inside and have also made sure to weigh it down for stability.
Looking at the FreeAgent Go Dock+ from the front, it does not look like much at all. You can see the single hard mounted mini USB plug and the slightly angled slot. The front has an interesting shape to it; it looks like it has a cut out at the front lip. This is because it does have a cut-out. The reason for this is to make sure that the larger capacity FreeAgent drives will fit in properly.
When you flip it around to the back you see the first indication that the Dock+ is more than a simple stand. Here you can see the three USB 2.0 ports that give the Dock its extra "+". Seagate has also removed the hardwired cable that was present on the original Dock. This does make for better portability. In the center of the backplane is what looks like a pin hole. This is actually a single green LED to indicate power to the device.
The power port is needed for full use of the USB 2.0 Hub and the Dock+ with just a single FreeAgent Go drive.
