Just tell a fool how smart he is by using your products. That way you get a cult following of fools believing they are smarter and better than those who prefer not buy over-hyped and grossly overpriced products.

 Remember when they convinced their cult members that using a mouse with only one button was superior? How about paying 20$ for something that a 1 cent paper clip would do (to open the CD tray)?

 And how about jail breaking is illegal. Or that the iPhone is the best phone. Or that Macs are immune to viruses.

 A fool will buy anything as long as they believe that owning the thing makes them superior.
