I heard a story of a American pilot accidently taking the no-go pills when he was supposed to take the Go pills during a cross Atlantic flight in his fighter. He got renamed "Coma" after that. I can't recall the youtube video though. :(
Not necessarily. I had the X-55 and got a lot of ghosting. I tried 2 different powered USB hubs and the problem persisted. I'd recommend OP save up a little more and buy the TM Warthog or Virpil, i think it's called? Just my experience/opinion.
