Query: Do NOT buy this! For many, it fails out of the box...

I received the MuVo 128 for Christmas. It worked great until just after the 90-day warranty expired. The power/play button locked up and would not power off. After pressing each of the buttons to try to unfreeze it, I finally had to resort to pulling the memory stick/player out of its battery case. After numerous emails to Creative's tech support and following their instructions, it still does not work. When I asked to escalate the trouble ticket, they chose to ignore me and closed the ticket. I replied to let them know how dissatisfied I was and that if someone didn't contact me by June 1, 2003 that I would begin contacting consumer watchdog reporters. No response. Currently, I preparing documentation and compiling negative customer reviews...to submit to a reporter who has contacted me. PLEASE DO NOT WASTE YOUR MONEY OR TIME ON THIS PRODUCT! ...
