This seems like a good way to increase storage for ipads. Especially since the price of SD cards is so reasonable. It also looks like an ideal way to transfer photographs from a camera without buying the camera kit. I wish that I had seen this a while ago. http://www.airstash.com/
This is really cool but a bit more than I'm currently willing to spend on something like this. It also concerns me a bit that the WiFi side of things currently only supports WEP for security. If it happens to drop in price and the new firmware supports better wireless security, I may have to add one to my travel gadgets.
