I saw these hot metallic bags on popgadget and I just had to share. For $130, you can get a Rock Steady beat bag which lets you plug in gadgets like your iPod, Nano, MP3 or CD player using the included cables. This bag by lifepod is powered by four AA batteries and has water resistant stereo speakers. Yes it's true ladies, you can bust a beat with this portable boombox on your way to the gym. I've seen bags like this before, minus the speakers, which kinda look cool. Do you likey?
