Why did Apple force this change on it's loyal customer base? Dont they know we humans don't adapt well to changes. Oh yes, we want the new shinny iPhone but we want it to stay the same AND get better.
Maybe this picture will give you a clue as to why Apple changed the connector. It shows a typical iPhone and it's 30 pin connector, with a Raspberry Pi. The Raspberry Pi is a full fledged computer on a board. Take a look at the board and the most obvious thing is all the connectors. The interface connections are the largest things. They occupy the most space.
