So then explain why you need all those pins and special cables just to charge a phone?
What pins? You mean in the 30 pin dock connector?
I'm not sure if you're being serious or just seem to have a technical blind spot when it comes to Apple. The 30 pin connector was designed as a "universal" connector. When it's in its charging guise (the most common form) with a USB plug on the other end then only the USB power and data pins are wired. Back in the early days (gen 2 iPod) it could also be wired with a firewire 400 plug on the other end, so a different set of those pins were wired.
It also had audio line out (unbalanced) on another set, for devices like speaker docks or car radios, and composite video and S-video (for docks attached to things with television screens) among other things.
The point was that not all the pins would be wired all of the time, depending on the current device or cable you were using. It was designed at a time when things like MHL wren't common. Android phones do exactly what the Dock connector does, with a variety of different cables using software and a protocol to change the output of the pins (allowing you to pass things like HDMI over a USB port, for example). The dock connector simply did this the old fashioned way.
It doesn't follow that this somehow means that the phone "needs" to be connected to a computer, and "all those pins" are certainly not needed for charging - when it's charging it needs only the USB power pins (and the data ones if it wants to negotiate with the host controller for more than 500 mA of current, beyond the USB spec).
The Lightning cable, on the other hand, takes its design cues from what Android has done with the USB port - cutting down the number of pins, and simply switching what they do depending on the cable, although they obviously aren't doing it with the same protocols (MHL etc). The big difference is that they went with a more mechanically solid connector because they felt micro-USB was too fragile (it is), and were thus also freed from some of the other limitations of USB (current and voltage specifications), allowing for high-power charging in future.
