This 4-port USB hub looks exactly like an old school tape, but if you try and play it in a Walkman, you'll damage it for sure. There's nothing sweeter than having new tech look like old tech. The cassette tape USB hub is a perfect example for this, and no it can't be used in a tape deck.
You can never have too many USB ports. That's why USB hubs are so useful, you can plug all of your gadgets in at the same time. However, not all hubs are made the same. The cassette tape USB hub isn't an exercise in efficiency, but more an exercise in style.
The cassette tape USB hub is available through the UK gadget shop I Want One of Those for about $24.
