Ars Technica highlights a new smart jacket that contains a 128MB MP3 player and a Bluetooth phone. The jacket has a built-in keyboard on the left sleeve and headphones and a microphone in the collar. When you want to place a call, the "stereo system becomes a headset and the music is automatically interrupted when calls come in." Pretty cool stuff even if it doesn't hold that many songs.
I found myself tempted by the BMW watch that has a built in MP3 player in it, good for about 5 hours worth of music. I regret that I am too broke to purchase.
