If you're like me, you probably carry a USB pen drive around with you, just in case you need to copy a file or 2 from someone else's PC. You might even go as far as keeping a couple of important apps or documents on that stick, just in case.
But imagine having hundreds of ready-installed applications on that drive, ready to access from whatever machine you plug it into. Never again will you borrow a friend's PC, or use a public computer, and not have access to an installed program that allows you to do what you need to do.
If this appeals, then what you need is a Pen Suite. This describes a collection of portable applications, ready for you to download and install to a USB pen drive. Then just plug it into any PC, fire up the built-in menu, and choose from all those wonderful utilities, games, diagnostic tools and so on.
If the thought of such a facility appeals to you, here are 3 pen suites that you might want to look at. They're all completely free of charge, and run under Windows XP and above.
First is Liberkey (http://www.liberkey.com/en/). The current version, 4.9, is available in 3 versions. The Ultimate version contains 168 applications and is a 215 MB download. It requires around 600 MB of installed space, so will easily fit on a 1 GB stick.
Second is WinInizio Pensuite (http://pensuite.wininizio.it/eng/). Again, the top-of-the-range version fits on a 1 GB stick. You'll find a comparison table of the contents of each version at http://pensuite.wininizio.it/comparison/index.htm.
Finally, Lupo Pensuite (http://www.lupopensuite.com/suite.htm). Once more, a 1 GB stick should be plenty to hold all of the 180 programs in the full version.
Although the contents of each suite differs, you can get a good idea as to the general make-up of each suite by checking out the categorised listed of Liberkey Ultimate at http://www.liberkey.com/en/suites/liberkey-ultimate.html.
