Use the built in USB Creator of the live CD (storage capacity for saving changes limitted 4 GB):

Or follow the following tutorial (larger storage capacity then 4 GB):

http://www.pendrivelinux.com has other great tutorials for installing different distributions to a USB drive too.

If you want to consider using another distro you might want
to try slax (it's based on slackware)
It can be installed on a usb drive and it's easy to
add additional software on it (modules) and you can also
save your configs

i have ubuntu 9.04 installed to usb fd (16GB), here is what i did:
- i make partition on usb fd using win xp and hitachi micro driver filter
primary 1, fat32/ntfs -data
primary 2, fat32 - some iso file, anti virus live cd
primary 3, ext3 - ubuntu 9.04
primary 4, swap (i am not linux guy, i dont know really know if linux on usb need swap partition)
- install grub4dos to usb flash, put grldr and menu.lst on pri 1 or pri 2.
- install ubuntu 9.04 (alternate install) to usb fd partition primary 3, and install grub to partition boot sector.
- boot ubuntu using grub4dos, (chainload to ubuntu partition boot sector or load kernel directly)

and here is what i got:
- Ubuntu on usb fd run on 7 different pc but not on ASUS P5Q
- Grub4dos will not boot on some HP pc if primary 1 formatted with ntfs, formatted with fat32 is fine.
