Guy Kawasaki on making presentations stick: translate technical specs into what audiences actually care about. Instead of gigabytes, say how many songs. Instead of miles per gallon, say yearly costs. Make the numbers mean something.

The next thing is to use salient points. First column is how we like to talk about stuff if you're into technology, but really the second column is what really counts. Miles per gallon, not so much. Yearly costs, much better. Degrees or heating costs, what should you set your thermostat for? Or a very easy example, do you talk in terms of gigabytes or number of songs. The salient point is number of songs, not how many gigabytes. I doubt that most normal people wake up in the morning and say, "God, if I only had a 64-gigabyte iPod, I would be happy." You talk about songs. How many movies can it hold? Use salient points.
