That's a nice picture. But it's completely irrelevant.
The new iPhone has a single connection port. Not 5 different ports like what you're showing in your pic. Combine all those functions of those 5 different ports into one connector, and then it would be comparable.
The new iPhone has to have a single connector, one port, that must transfer power, multiple audio channels both in and out, video in and out in multiple formats, data transfer in and out, etc. All that has to fit into one connector while keeping all those different functions separated from each other. For the 30 pin connector, each of those 30 pins would be considered a separate "channel" so to speak. Lots of those are bunched together for a single function, but that should give you the idea.
Just micro USB doesn't provide enough separate "channels" to transfer all the stuff in and out of the iPhone. Something new had to be created.
