The thing which caught my attention was the estimated costings (from a computer geek website DailyTech, so I dunno if they are good!):
"Costs for the program have ballooned from $30 billion USD in 2002 to $40 billion USD today. And according to the Air Force, a single F-35 will cost $100 million USD when production is comfortably underway in 2013 -- this compares to $50 million USD for a single F-16 or $132 million USD for a single F-22 Raptor."
Man who would want 4 JSFs when you could have three Raptors! An it saves on pilot costs
