I wish I would have discovered this tool earlier. After being in Southampton for less than half a week, I am starting to miss the applications on my PC back home. On streaming one of my fave shows on the net, BBC's Click, I found out about PortableApps.com.
PortableApps.com is a free application that allows you to install and run your applications from your USB drive hence allowing you to bring all the applications you want with yourself everywhere you go. As the name implies, you can make your applications portable.
Browsing through the website, I also found a list of free applications that I can download which includes sudoku games, office suites, web browser, e-mail clients and etc.
I have not personally tried it yet due to time constraint but will do so the soonest I get a chance to.
Well, that's all from me now and I better get showering for another productive day at work.
