PortableApps Suite, runs software on a 512MB flash drive

Need to run a bunch of applications but either can't install them on the computer you are using temporarily OR you don't want to install any software.

With a 512MB flash drive you can run portableapps, including Firefox, OpenOffice and a bunch of other applications. Never leave home without it.
