Portable Application Suite on Thumb Drive

At my work all the computers have a standard software package and individual users cannot install additional software. I use Firefox, open office and putty on a regular basis on my personal computers and have things setup to get my work done efficiently. To my surprise, I found a "suite" that could be installed on a thumb drive (usb key) that would allow me to use my favorite applications in a portable fashion: PortableApps.com. From their website:

Free

The PortableApps.com Suite and Platform is free. It contains no spyware. There are no advertisements. It isn't a limited or trial version. There is no additional hardware or software to buy. You don't even have to give out your email address. It's 100% free to use, free to copy and free to share.

I installed the standard portable suite which is a complete collection of portable apps including a web browser, email client, office suite, calendar/scheduler, instant messaging client, antivirus, audio player, sudoku game, password manager, PDF reader, minesweeper clone, backup utility and integrated menu, all preconfigured to work portably.
