Here's a simple technology truth I think is worth considering.
If you want someone to get on board with MP3 players and the technology seems foreign to them, simply extolling its virtues more might not do the trick.
But when you offer the following continuum — record, 8-track, cassettes, compact disc, MP3 players — you've now put the new technology into a context they can more readily understand (and potentially accept and adopt).
While many of us might get excited by the newness of some technologies, others are more likely to accept them (i.e., iPods) as a new form of a function (listening to music) they've already accepted.
While the example I have given is about technology, I think the basic premise holds true when introducing just about any type of change. Put the new or strange in the context of the accepted and familiar and you are more likely to get heads nodding.
