Open Office has a Portable version in BETA. Install it to your flash drive and take it with you.
Time to think about Open Office as a serious competitor to MS Office.
OpenOffice.org Portable is a fully-functional package of OpenOffice.org
optimized for use on a USB key drive. It has some specially selected
optimizations to make it perform faster and extend the life of your USB
key as well as a specialized launcher that will allow you to launch it
from the directory of your choice. It will also work from a CDRW drive
(in packet mode), ZIP drives, external hard drives, some MP3 players,
flash RAM cards and more.
