A USB flash drive is a small device, about the size of a stick of gum that you plug into one of the USB ports on your laptop or desktop. They don't require batteries, and don't have to be recharged. You can buy a 1GB size USB flash drive for about $40, and a 2GB flash drive for about $89. I used to use a palm pilot for my personal to do list, contacts and calendar and an iPod to hold music to listen to while I was at work. That is until my brother told me that I could export Outlook contacts, tasks and so on to a USB and update it from there. I then decided to try copying music files over as well. Not only did that work, but I can play music off of the USB flash drive using Windows Media Player. I now use only a USB flash drive (it's password protected) at work. I can keep track of my personal contacts, calendars and things to do, while listening to music. The downside is that the capacity is limited, so I can only store about 20 hours worth of music, and unlike an iPod or a palm pilot, I can't update it without a computer. Of course, for me, these aren't problems, I always used my palm pilot and my iPod at work. On the plus side, it's cheaper than having a palm pilot ($199) and an iPod (about the same price), it doesn't need batteries, doesn't have to be recharged and doesn't have to be synced with Outlook.
