Very dull content for anyone who has worked on anything related to mobile phone HW during the past 20 years. Every manufacturer has similar prototype boards and there is nothing special in this iPhone prototype.
I realise that this was probably said in an effort to appear worldly in an “I knew the dog before he came to school” sort of way, but it does a good job of illustrating how working with cool tech can sometimes desensitize one to the fact that it is, after all, cool. I bet rocket scientists think rockets are kinda boring too, after a while.
I can't imagine somebody would say this, but you might be right!
