FireWire KeyChain is the industry's smallest portable, self-powered firewire storage device. It was designed and built based on customer input at the Macworld Expo show in early January. Many of its features will make it more appealing than current portable USB storage devices.

Except the fact that I have to also carry around a firewire cable with me at all times to use this device. Every USB keychain device I have seen can simply plug into a USB port with no necessary cable. Thats the bigest flaw I saw, and can't believe they haven't fixed it yet.
