    I love technology! My first PC hard drive held 10 MB and cost $600, so I appreciate high capacity and low cost. I bought this after renting a car with a USB drive jack for the sound system. I copied my entire MP3 library to this flash drive, plugged it in, hit "Shuffle", and travelled for a week without ever hearing the same song twice. Highly recommended!
