In Virginia, patrons waiting in line to buy county school surplus iBooks for $50 
started a riot when the doors opened, with an old man getting trampled, people crushing a baby stroller, and someone trying to run people down with his car.  One iBook hopeful admitted that he used his folding chair as a weapon to fight off people who were trying to cut in line.  Take a lesson from Steve Jobs, Henrico County: make them a little more expensive, and prevent the bloodshed.  (Editor's note for the humor-impaired:  no, I don't really think Macs are too expensive.  I'm making fun of people who do)
