I just wanted to tell you guys about the Nike Philips MP3Run. I was able to review one for a store that sponsors me. I love to wear an mp3 player when I'm training and this one was one of the best around. But the reason I love it is because of the BLUETOOTH wireless transmitter/pedometer that attaches to my shoe and tracks the distance, speed, and time of my run. There is a female voice that speaks over the music every interval at which you want it to tell you your progress. It's nice because I don't hvae to look down at my watch everytime to track my time. I can just concentrate on my run and allow the headphones to dictate how I am doing. I would not be surprised if BLUETOOTH based products start popping up more and more in sports. Without wires, you can pretty much do whatever you want while participating in extreme activity. It's awesome. 2 THUMBS UP
