Calling a USB 2.0 cable in 2012 'Lightning' is a bit ridiculous if you ask me.
'Slimline Dock Connector' would be better, but lightning-speed it is not.
Remove the word dock and you're right (Apple seems to be anti-dock these days). Apple expects you to do everything wirelessly these days so it is pretty much the power cord but can also transmit data for people who are still using iTunes to maintain their iOS devices (I'm sorry if you are because man iTunes 10 is bad).
