OpenOffice.org on Portable USB drive

My favorite Office suite is OpenOffice.org which is free and fully functional alternative to Microsoft Office 2007. If you haven't tried it yet, I highly recommend OpenOffice.org to you.

However, OpenOffice.org is not widely available on computers in offices, cafe, schools and airports. In case you want to use OpenOffice.org on public computers without OpenOffice.org installed, you can install OpenOffice.org onto your USB flash drive beforehand, carry it with you wherever you go, and run OpenOffice.org from the USB thumbdrive. OpenOffice.org can be installed on USB thumbdrives of minimum 512 MB space. There are 2 portable releases of OpenOffice.org:

• U3 release of OpenOffice.org
  
  This version is outdated 2.2.0.0 and cannot be run on non-English versions of Windows.
  
• PortableApps.com release of OpenOffice.org
  
  This version is the latest 3.0.1 and can be run on all versions of Windows and also on Linux. Thus, I recommend PortableApps.com release.
