I saw these hot metallic bags on popgadget [1] 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 [2] 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?
