@offhand.yt: When Steve Jobs held up the first iPhone at Macworld in January 2007, the phone in his hand was pre-production hardware that crashed if he opened the apps in the wrong order. He rehearsed one exact sequence, the golden path, and never stepped off it for the whole demo. The signal strength meter was hard-coded to show five bars so nobody in the room would see the connection drop. Apple's engineers sat together in row five of the Moscone Center, drinking scotch every time the demo survived another step. #stevejobs #iphone #apple #macworld2007 #techhistory #DidYouKnow
