And if
theducks should happen by - I dont carry a usb stick, too easily lost or forgotten, I carry a 80GB shirt pocket size drive and a longish usb cable - as well as data it has portable firefox, open office, notepad++ etc. Many public computers allow you to run programs off a portable drive, such as my local libraries, coin in the slot machine in shopping malls etc.
My latest stick is 64GB USB 3.0 job - came gift wrapped. I use it for Windows ReadyBoost, whatever that is.
