Creative is going to release “ZN-Z32G-BK”, a credit card-sized portable MP3 player, in Japan market with a price tag of 39,800 Yen. This device is so slim that you can even place it on your wallet. However, its small size doesn’t mean small capacity. Inside, you can store up to 32GB of music, or about 8,000 of your favourite songs. I supposed it’d play all of those popular audio formats, such as WAV and MP3.
