The Eizo C@T-one from Nanao Japan is a roundish mouse that also doubles as a TV remote. The wireless mouse works on the 2.4Ghz frequency, has a scroll wheel and an optical sensor which turns off automatically after 30 minutes in order to save power. It also sports a tilt sensor similar to the iPhone, so that when you tilt the mouse it activates the remote control.
It’s got all of your typical controls like power on/off, channel and volume control, mute etc. The device is powered by AA batteries which supposedly last for 3 months. The USB receiver is about the size of a pen drive and it’s compatible with Mac and Windows. Currently it’s available in Japan only for about $ 125.
