But however you feel about Apple's dumb, expensive adapters, you're going to need new cables at some point. Apple's got them for you now. It just announced Lightning cables that connect to USB camera adapters and SDCard adapters, HDMI, and VGA.
Those might not be as crucial as your basic charging cables, but it's nice to have the option now. While Apple's not confirmed UK pricing yet, over in the US, camera adapters are $30 a piece, and the AV and VGA adapters are $50. Expensive, annoying, and sadly necessary.
