OCZ has added on to their offering of flash devices, with the introduction of a new USB 2.0 flash drive. The Ultra-Portable Spyder USB 2.0 drive will feature 2GB, 4GB and 8GB capacities, aimed at offering flash storage with extreme speeds. Supposedly the unit will be able to read at up to 35MB/sec, putting it at the high-end of USB flash storage speeds. An off-the-shelf 2GB unit can often be abysmally slow, which is why for any real serious data transfer a USB portable drive is preferred. At those speeds, a keychain-sized flash drive would be very handy.
They also have a 1-piece design that prevents you from losing the protective cap over the USB connector. You can read more about the unit in their press release or on the Spyder's product page. The price range of these units isn't astronomical either, with prices in the $45 range for the 8GB model.
