All the time I read suggestions on using USB sticks and I must say
people are crazy about USB sticks. It is more convenient to use optical
media then USB stick because they are read only. Boot from Live CD, not
from USB stick and use USB stick only for data. In a desktop PC you can
put two CD devices and boot Live CD from CD1 and write your data to
CD2. You can use write-once media or rewritable media so you do not
waste to much plastic.

If you write your data to CDROM, then it is much more safer to transfer
data to another PC. It is much more complicated to make a virus that
will insert itself into a CDROM then into a USB stick. Furthermore,
such action would be odd and could be blocked by a security software
like SELinux.
