I went to a steak house last week, the steak was good. I went back to the same steak house a few days later, the steak was overcooked, the chipsets on the N9's are like this different days and different steaks, no 2 chips are exactly a like. I got an ok steak and I'm fine with that. Learn to accept that you won't get a perfect steak every time you go to the same steak house.
