Query: 7 Years and Still Perfect

I purchased this in spring of 2004 and I still use it on a daily basis to this day. It still works as though it's mint condition.The quality of sound is amazing, especially when using the right headphones (Sony Lightweight Headphones).The capacity is more than enough for me because I refuse to believe that ANYONE needs 40 gbs worth of music. Seriously, who listens to 40,000 songs?The size is perfect for portability. I take it with me everywhere.They battery has dwindled only slightly, but thats to be expected in it's seventh year of life.And for those that experience issues with using it on anything newer than XP, there is a driver created specifically for the ZM to be used on updated OSs.
