The Belkin Digital Camera Link is almost as big as the iPod, holds two AA batteries, and has some flashing LEDs, and a button that initiates the transfer. One reason the Belkin device is so large is that the connector cable stows inside of it.
When I first read the review, I figured that this device is a card reader. (Remove the memory card from the camera, and stick it in the Belkin unit?) No. It has a mini USB port: you connect your camera using its USB cable.
That troubles me: using USB leads to compatibility problems. For example, my daughter's new Casio camera has a proprietary connector built-in; she needs to haul around the docking station, which uses the square USB connector. I also wonder if some digital cameras might not connect via the USB connection.
If the Belkin unit were a card reader instead, then my daughter could just pull the memory card, and plug it in -- no need for the docking station.No compatibility issues.
Back to the The Register's comments: You cannot view photos on the iPod, but can see a list of filenames. Photos are stored in their own folder. I could see Belkin introducing similar devices for other hard-drive-based MP3 players.
