I saw this at a store this weekend, and thought it would be a great travel hub for the MBA:

Some nice things about it:
1. Small.
2. Has 4 ports.
3. Has a thumb drive dock type port in the middle (the thumb drive would stand up when inserted).
4. One port is both a regular usb port and also a mini-usb port, so no additional cable needed for mini-usb devises (external HD, camera etc).
