Does it look like this? Is it worth $30?

I think it looks much better than hacking that SD card in half with a saw or something.
As for value, it's totaly up to the user. $30 does seem a bit steep for what is essentially a microSD adapter. I would put it like this:
- If you need extra low-speed storage in your MBA, and you can make something similar to this in less than an hour, then $30 is not worth it.
- If you don't need low-speed storage in your MBA, then $30 is not worth it.
- If you need extra low-speed storage in your MBA, don't feel like futzing around with breaking SD cards, and would rather just buy an off-the-shelf solution, then the $30 is well spent.
