I have seen that video. And I found that this is nothing but another method of getting attention from the YouTube users. It has not much proved it's point that why there is no use of the headphone jack. What they are trying to show is that what the apple marketing team is making for the removal of the headphone jack.
They have made this sort of changes with the other Apple models too. For example the power plug and the USB ports were replaced in the apple's AIR. The single port makes a lot of difference with the consumers considering they need USB hub to be used for multiple connections. And for that reason there is a lot of criticism.
Problem with apple is that they think in order to achieve minimalism and so-called style, options need to be removed. But in reality, everyday life requires more options. Not having USB port in laptop, not having headphone jack in iphone. They are just cutting the options of people. And the other companies are forced to innovate to filll in the gap.
