Sad thing is that sales folks even at places where you think that they should know better use this. I had a sales guy at a local camera store tell me straight faced that I really wanted to get the more expensive camera because it had 8.2 m-pixels where the one I was looking at had only 8. He said that when I would print, instead of a 5x7 I would get a 4 1/2 x 6 1/2 because of the fewer pixels.
Maybe if you print at about 600DPI
