Yamaha announced a new speaker cube called the "NX-A01" which was developed with the W41T in mind -- not only does it support Bluetooth with its matching receiver, it handles the MPEG-4 AAC HE codec used in au's new "au LISTEN MOBILE SERVICE (LISMO)." Long story short, you can wirelessly download CD-quality tracks using the new service (onto your phone's 4GB hard drive), and you can play them on your speaker cube without messing around with cables. The speaker itself costs 13,000 yen, and the Bluetooth module 14,000 yen, bringing your total to about $234 USD.
