You know, one of my biggest pet peeves is when I see people walking around using or just wearing a Bluetooth headset. In your car that Bluetooth is fine, but when you have the time to actually hold the phone so we know you're not crazy, please do so. Thanko has announced a new MP3 player called the Microsports MP3 player that is so tiny it looks like a Bluetooth headset more than an MP3 player.
The device measures in at 16 x 25 x 22mm and is available in 2GB or 4GB capacities. The device has a thin cable that snakes around your dome to allow you to listen in stereo too.
The small device weighs only eight grams and has an ear loop to keep it in place. The thing sells for a $55 for the 1GB and $76 for the 2GB version. That seems overpriced to me and people may hate you because they think you are wearing a Bluetooth headset while walking to boot.
