The Seagate USB 2.0 Pocket Hard Drive is less than three inches in diameter and comes in 2.5 and 5.0 Gigabyte sizes. It has a retractable USB cord included and (according to the computer magazine I’m holding) the 5GB should cost $160 street. Convenient and cute. I haven’t personally seen one, but we all should be familiar with Seagate hard drives.
