Before I bought this flash drive, I always had to tinker around and find some clever way to get a certain program/file onto another computer that was in need. Now with this thing strapped onto my keychain, it's with me everywhere I go. It is extremely useful when I get called over by one of my friends to help them with a computer problem, or something with the internet not working and so forth. At many times, it is that my friends freshly installed their operating systems and have no internet drivers. Most of the time they dont have a motherboard cd or somthing like that because they bought the computer whole from Frys or Best Buy, even Circuit City...haha. I usually have to make a quick run home, go on google to look up drivers for the make and model of their computer. In a few easy steps, Download, drag and drop to flash drive, bring over to friends house and install. Boom! I am a hero and supernerd :D. It also makes me look smart cuz I'm always carrying this around with me.
