In Praise of Obsolete Media (apolgies to CTL)

Very few people use cassette tapes anymore. I don't even have a working tape player these days. But it turns out that CDs are no good for classroom use.
First of all, the geniuses who bought the CD players in the classrooms picked the cheap ones with no pause button. Try teaching an English lesson on a CD without stopping the track.
Second, in classrooms with hardwood floors, kids jumping up and down cause the CD to skip wildly. So I've had to copy all the CDs I use on to old cassette tapes to use them at all. Which is too bad in a way, because they're missing out on hearing "The Hello Song" in all its hi-fidelity glory.
