I bought this when I was finishing up my marketing degree in fall 2007. Just plug it into a USB port and it pops up as F: or G: drive (depending on the computer). Holds 32 MP3s, 80 JPEGs or 22 minutes of MPEG4 movies according to the packaging. It had enough room for me to work on a video project and 3 versions of a sales presentation (one in Word, one in Power Point and one in Publisher) simultaneously and transport them between home and school. A must-have school supply these days.
