Bought a 256 Meg Speed Drive for about 80 pounds UK. Came with a lead as well so you can either plug it straight into the USB port on the computer, or if its a bit tight, plug in the lead and then plug the drive into the lead. Its a great bit of kit - I can truck my university assignments around with me and use pretty much any machine with M$ Word on it. Understand you can get up to a gig in them now.
Cheers
