It seems that the more things change, the more they stay the same. Here's something from the first edition of Using Information Technology, a thick "practical introduction to computers & communication" written way back in 1995:

Anticipointment, as Berkley, California, editor Hank Roberts explained in an online computer conference, is a word coined "to describe always finding that, just as the techie-toy I've been dreaming about getting for six months has become affordable, there's something so much better on the horizon that I guess I have to wait just a bit longer."

Maybe the only difference today is that six months is nowadays as short as weeks or even days?
