The Gadgeteer has a review of a 1 gigabyte FireWire keychain from WiebeTech, which is basically just some CompactFlash memory with a FireWire port all in a 2.35 inch by 1.75 inch metal box. Hopefully this will mark the beginning of a trend towards using high-speed connections like FireWire and USB 2.0 for these pocket storage devices, rather than USB 1.1 which can be agonzingly slow for transferring anything larger than a few megabytes.
