Over one year after taking over struggling audio equipment maker Aiwa Co Sony plans to release the card-size Giga pavit HZ-WS2000 Measuring 10.6 millimeters thick and weighing 68 grams Making it the worlds thinnest and lightest music player among those with a hard disk drive HDD Sony said in a news release Although this is very questionable as seen in the photos the HZ-WS2000 requires a controller type device to operate Not an ideal design standard in my opinion
