Am I the only one who finds this kinda... well... dangerous?
I know, it's the logical next step of the iPod generation, carrying that little bubble of music with you everywhere (and I say that at someone rather fond of her own personal bubble of music -- I do wear my headphones a lot while commuting (by bus!!), walking, etc. I embrace the rejection of community implied by the headphones! I embrace my musical isolation! Ahem.). But... yikes.
Well, I guess it's better than those little bike-mounted radios. If you're wearing headphones you're only potentially killing or injuring yourself (and, of course, whoever you run into or are run into by). But those little radios are annoying for everybody.
