I am convinced that one of these days they are going to have a way to implant the music directly into our brains so that we have no wires to have to contend with.  For now, the next best thing could be the Rock-It portable vibration speaker.  It looks slightly like a speaker you might put under your pillow, except it has a pod that you stick on any flat surface.  It could be a box, a window or the side of your file cabinet just so long as it’s flat and it will stick.  Plug in your iPod, iPhone or anything that has a 3.5mm headphone jack and then that surface becomes your speaker.  It is available now for only $29.99 direct from Pyramid Distribution.
