"Once you switch your install to a flash drive, it means you can
take it pretty much anywhere and get back to work immediately.
Whether you're using a server, a desktop or even a tiny little
Aspire One or Eee PC, the vast majority of modern computers support
booting straight from USB, so you can just plug in your drive and
go.
"You'll need a flash drive with at least 1GB of free space, and
ISO images of either Ubuntu 8.10 or Fedora 9. It's likely there are
other distros out there that work with similar or perhaps even
identical instructions, but Ubuntu and Fedora are the big two so we
stuck with them."
