Why does Apple still do business with Samsung after so many years of failed negotiations, bitter protracted trials and a series of massive ad campaigns where Samsung has both ridiculed Apple and its lined-up customers while at the same time claiming ownership of delivering the next "one more thing" that people might want to queue up to get?
