In the obsolete technology dept.--do you remember in the mid-90s when massive CD-changer stereo systems were all the rage? 100 CD changers! 300 CD changers! Holy shit how high could it go!?!? It was kind of like a Babbage Engine form of the iPod. I just checked on some prices and, although this probably isn't definitive, a 300 CD changer is now cheaper (i.e., less desirable) than an iPod.
