I am a avid mac user and it goes without saying that I am inturn an iPod owner. How many out there use iPods in your gym? How many know about the in-earphone? Because I am in Korea my gym plays a lot of really crappy music. My iPod has saved me! And the in-earphones block out all external sound (not so good when I almost get hit by a bike on the sidewalk). What's on your iPod? Cheers!
