If you're like me, your USB key should come with its own flame retardant coating. That's because I tend to use my little four-gigabyte device to great excess on a near-daily basis. It's an easy fix for transferring files from a desktop PC to a laptop, and it's great for carrying batches of files I need to access (especially if I'm without an Internet connection, making Dropbox useless). If I'm heading over to a friend's house, I can slap a movie on the drive for us to watch on an attached PC or home theater device. I can throw down a game or two if I'm going to be travelling and don't feel like reading about overpriced devices that will pet my cat for me. USB keys are more than just a geek's trusty friends. They're uber-tools in their own right.

Application suites for USB keys are another popular way of extending the functionality of your desktop into the portable realm. Install these batches of software and you can take your favorite programs along with you wherever you go--perfect for when you're using a computer that isn't yours, yet you would prefer to be able to access to a better range of apps than Windows' default programs. Better still, you can stick these batches of applications on smaller USB keys to extend the life of these sub-gigabyte devices. The storage might stink, but the functionality will rule.

Click the jump to check out five, freeware application suites that will dazzle up your USB key faster than you can say, "universal serial bus."
