Get the Portable Apps suite from
PortableApps.com - Portable software for USB drives | Your Digital Life, Anywhere™ - Only Open Source high quaity apps in a very functional menu.
I've been using them for a couple of years and now have over 60 apps on my USB 80Gb HDD.
Download the main suite and then have a trawl through the forum in the beta testing thread as there are lots of other apps that work really well in there.
Here's some examples for you to Google
